c/coding-for-beginners

My Python script kept crashing after 100 lines until I added one simple check.

I was pulling data from a website for a school project and the program would just stop every single time. Turns out I wasn't checking if the webpage element existed before trying to grab its text, so it would fail silently. What's the most common beginner mistake you've had to fix in your own code?

I tried making a simple game with two different beginner tutorials...

The first one just gave me code to copy, but the second one from a site called 'Codecademy' made me type each line myself and explained why it worked. I actually remember how to fix things now when they break. Do you learn better from copying code or writing it out step by step?

I finally got why my simple calculator app kept crashing...

I was trying to make a basic tip calculator in Python for my friend's cafe in Springfield, and it kept giving me an error every time someone typed in a letter instead of a number. I spent like 3 hours last night staring at the code before I realized I wasn't checking the user's input at all. Has anyone else had a program break because of bad input and found a good way to handle it for a beginner?

My friend told me to learn JavaScript before Python and I'm not sure it was good advice

When I started coding six months ago, my buddy who works as a web dev said to go with JavaScript first because it's 'everywhere'. I spent three months on it and got really stuck on concepts like async functions and the DOM. Last month I switched to Python for a small project and found the syntax way easier to follow for a beginner. Now I'm wondering if starting with a simpler language would have been better, even if JavaScript is more common for web stuff. Has anyone else been given advice to start with a harder language and regretted it?

Changed my mind about learning Python vs JavaScript first

I was set on starting with JavaScript because everyone said it was easier for web stuff, but a free online course from freeCodeCamp made me switch to Python. After doing their first 10 lessons, the way Python reads like plain English just clicked for me way faster. Has anyone else picked a first language and then totally switched after trying a different one?

My uncle told me to start with C++ and it was a disaster

He's a game developer and swore it was the 'only real language' to learn first. I spent two weeks in my apartment trying to set up a compiler and write a simple 'hello world' program, but I just got pages of scary error messages. I finally switched to a beginner Python course online and made a little number guessing game in one afternoon. Has anyone else gotten really bad first language advice from a family member?

Just got my first Python script to run without errors after two days of trying

I was trying to make a simple program that asks for your name and then prints a greeting. For two days straight, it kept throwing a 'NameError' because I kept messing up the variable. I finally realized I was trying to use the variable before I actually defined it. Fixed that one line and it worked perfectly. Has anyone else gotten stuck on something that simple for way too long?

I spent $300 on a coding bootcamp that just taught me how to copy and paste

I saw an ad for this online course promising to make me a web developer in 12 weeks. It was a lot of money for me, but I figured it was an investment. The whole thing was just video lectures where the instructor typed code and told us to type exactly what he did. No explanation of why things worked, no real problem solving. When I tried to build something on my own after the course, I was completely lost. It felt like I'd just paid to watch someone else work for three months. I didn't learn how to think like a programmer at all. Has anyone else had this happen with a paid course? What's a better way to actually learn the logic behind the code?

Vent: My first project crashed because I didn't know about memory leaks

Last week, I finally got my little weather app to run after a month of work. It pulled data for my city, Denver, and showed the forecast. After about 3 hours, it just froze and shut down. I spent two whole days trying to find the bug, and it turned out my loop was creating new objects every second and never clearing them out. I had no idea that was even a thing you had to manage. How are you supposed to know about stuff like that when you're just starting? Has anyone else had a simple project blow up from something you never learned about?

I used to think you had to memorize every single function before writing a line of code.

After I built a simple calculator last month, I realized you just need to know how to look stuff up and start building. What's a small project that helped you get over a learning block?

Overheard a senior dev at a coffee shop say 'just copy the Stack Overflow answer' to a new hire and it made me pause.

My project went from a mess to working in about 3 hours after I learned about version control

I was building a simple to-do list app with HTML and JavaScript, just following a tutorial. I kept making changes, breaking things, and then I couldn't figure out how to get back to the last version that actually worked. I lost almost a full day's work last week trying to fix my own mistakes. Then a friend told me to just use Git. I set up a GitHub account and started committing my changes. The difference was crazy. Yesterday, I messed up a function that handled deleting tasks. Instead of panicking, I just used 'git checkout' to go back to my last commit. In maybe 10 minutes, I was back to a working version and could try a new fix. It felt like a superpower. Has anyone else had a moment where learning one basic tool completely changed how you code?

I kept getting stuck on loops until I started drawing them out with a pen

I was trying to make a program that printed numbers 1 to 10, but it just kept running forever. After staring at the screen for an hour, I grabbed a notebook and drew a box for the starting number and arrows for each step. Seeing it on paper showed me I forgot to increase the number inside the loop, so it was always checking '1'. I fixed it by adding 'i = i + 1' and it worked first try. Now I sketch any tricky loop before I even type the code. Has anyone else found a simple trick like this that finally made loops click?

A code review comment about my variable names made me rewrite a whole project

I showed a small script to a friend who codes for a living, and he said 'I have no idea what x, y, and z are supposed to be.' I was using single letters for everything. I spent last weekend going back and changing them all to clear names like 'user_input' and 'result_count'. It was a pain, but now I can actually read my own work. How do you guys pick good names without making them too long?

Watching people try to learn Python without writing a single line of code themselves is wild.

They just watch videos for weeks and then wonder why they can't solve a basic problem. Has anyone else seen this and found a good way to tell them to just start typing?

Showerthought: My kid's friend Jake said coding was just typing and it clicked for me.

He was over at my house last week, watching me fix a simple website bug, and said 'so it's just typing words?' I told him it's more like giving the computer a very clear list of steps, like telling someone how to build a birdhouse. We spent 20 minutes writing a tiny program that just printed his name 10 times, and his face lit up when it worked. What's a good first project for a 12 year old who thinks coding is boring?

Tried to make a simple counter in Python and it kept adding by two

I wrote a loop that was supposed to add 1 to a variable each time, but I accidentally put the print statement inside the if block. After three tries, I realized the counter only updated when another condition was met. Does anyone know a good way to practice spotting these logic errors?

My friend said I should start with Python, but my cousin swears by JavaScript

We were at a barbecue last weekend and I mentioned wanting to learn to code. My friend Mike, who works in data, told me to start with Python because it's 'simple and powerful.' Right after, my cousin Sarah, a web developer, jumped in and said that's bad advice, and I should learn JavaScript first to 'see results in a browser right away.' They argued for like 20 minutes while I just stood there holding my plate. Now I'm totally stuck on which one to pick for my first language. Has anyone else been given completely opposite advice from people they trust?

PSA: My first real project crashed after 3 hours of work

I was trying to build a simple weather app in Python. Got the API key, wrote the code, everything looked good. Then I ran it and got a wall of red error text. Turns out I forgot to import the requests library. Has anyone else had a simple mistake ruin hours of work? How do you check your basics first?

My portfolio site went from 5 seconds to load down to 1.5 after I compressed my images

I didn't realize how much my huge PNG files were slowing everything down until I ran a speed test last week. Used a free tool called TinyPNG and it made a crazy difference. Anyone else have a simple fix that gave their project a big boost?

I finally got why my python script kept breaking after 3 years of just copying code from stack overflow

Last month, I spent a whole Saturday in my kitchen trying to fix a script that pulled weather data, and I realized I'd never actually learned what the 'if __name__ == '__main__':' line at the bottom of my files even did, so I just started reading the official python docs for the first time.

I thought learning to code with just a phone was a total joke

For months, I was convinced you needed a full computer setup to even start. I was stuck with just my phone and couldn't afford a laptop, so I figured I'd wait. Then a friend told me about an app called Sololearn. I downloaded it as a joke, honestly. But after a week of doing the Python lessons during my bus commute, I built my first tiny script that sorted a list of names. It wasn't fancy, but it worked. The app's little code editor and community challenges actually made things click in a way I didn't expect. Now I'm saving for a laptop, but I'm not stuck waiting anymore. Has anyone else started coding seriously on just a mobile device? What apps or tricks did you use?

I used to think you had to get everything perfect on the first try when learning to code.

I was working on a simple weather app project last Tuesday night. I was trying to make an API call to get the temperature for my city, Portland, but I kept getting an error. For two hours, I just stared at my screen, trying to find the one perfect line of code that would fix it. I was getting nowhere. Finally, I just started over. I deleted the whole function and typed it out again, slowly, checking each step. It worked. The mistake was a tiny typo in the variable name I'd copied. That moment made me realize that coding isn't about being perfect. It's about trying, breaking, and fixing. How do you all deal with getting stuck on a small bug?

I finally got my first Python script to run without errors after three days of trying.

Last week, I was stuck on a loop that kept printing forever until a friend in Seattle told me to check my indentation, and it worked on the very next try, so what's the one small bug that took you way too long to fix?

I just hit 100 lines of code that actually WORKED

I've been trying to learn Python for a month, mostly just fixing errors. Yesterday, I wrote a small program to sort my grocery list and add up the cost. It was 100 lines long and ran perfectly the first time. I've never had that happen before. It felt like a real win after so many small fails. Has anyone else had a moment where a bigger chunk of code just clicked?
