Codecademy - Python: Tutorial #11

Enroll for coding exercises, projects, tutorials, and courses...

This is part 11 of the Codecademy Python Walkthrough Tutorial. It covers topics like a Day at the Supermarket, dictionaries, functions, lists, compute bill, incrementing, decrementing, dictionary loops, list loops, for loops, control flow, conditional statements, arguments, more practice with lists and dictionaries, and much more!

======================= ABOUT PYTHON CODECADEMY SERIES =================

The target audience is beginners or developers looking to pick up Python. I also emphasize the importance of writing good code and I go through the first part really fast.

I will literally be going through every single thing and breaking it down for you so there is nothing for you that would be scary. You can watch me do it and you can simply follow along you will learn ALL the basics. I swear I wish something like this was out there when I started learning because everyone else explains things in such a complicated way and makes it so boring! I honestly think programming is based upon exploration and creativity rather than some mathematical/logical genius frame of mind! I spent a lot of hard work in making this so I hope you guys enjoy and learn something out of it while having fun! This is targeted towards beginners, for developers looking to learn python, or for individuals looking for a refresher on basics in computer programming!!

Thanks for translating the conceptual concepts by inserting tangible examples to the expressions. Really really helps a lot.

had to stop for the brain comment true story i been stuck wrecking my brain understanding everything from for loops to this....i felt my brain actually like grinding with me trying to figure it out the next day after i get home from work i start to write a simple menu and an entire program just vomits out of my fingers into code talking out loud explaing to my self step by step what i was doing created an app that takes the item you oreded asks how many plates you want of each item on the list mulitpy it gives the total of each one, and then of course made some fun input for my girlfriend to interact with and it runs like a charm like a 3 second program but it contains all lists for loops dictionaries decrementing input vaiables but it was so much fun at the end i didnt know what to do so i just went back to learning ....quazi!!! shout outs bro you are the

Just wanted to say thanks. I have thought about learning programming for year and together with Codeacademy this is a perfect way, my new year resolution is to learn a basic level of python and thanks to you it's just up to me to do it. Great job with the channel.

For making a purcashe exercise I am doing the exact same thing as you:
def compute_bill(food):
total = 0
for item in food:
total += prices[item]
return total

but still gives me the error:Oops, try again. compute_bill(['banana', 'apple', 'orange', 'pear']) returned 4 instead of 10.5


Please help

Why Does It Matter If It's "For Item In Shopping_List" OR " In Food"?
