11:45 you don't need to escape a single apostrophe if the string uses double apostrophes. Likewise, you don't need to escape a double apostrophe if the string uses single apostrophes. For example, print("Glad that's all over!") and print('Glad that"s all over!') will both work. It's only an issue if the string and the escape use the same single- or double-apostrophes. Awesome video BTW!

Thanks

11:45 no need to escape the apostrophe since it is enclosed in double quotes.

Just wanted to say thanks for the awesome content on your KZbin channel! I'm learning a lot from you and it's really cool to see kind-hearted people like you out there. Keep up the great work!

[@DaveGrayTeachesCode]

Awesome, thank you!

I like how I am able to solve little problems on my own thanks to your sensible teaching Dave a little progress everyday goes a long way, progress over perfection

[@Omer698]

Thank you for the video. One of the hardest thing about coding for me is the order in which you type things out like you mention in the continue section (3:40) I wish more teachers would focus on that

Amazing Dave! You are relentless 💪 Congrats on the 150k subs, very deserving of such and more.

[@DaveGrayTeachesCode]

Thank you very much!! 🚀🙏

FWI, for the print("Value is now equal to " + str(value)) statement could be rewritten as print(f"Value is now equal to: {value}")

[@codehound8033]

You are an excellent teacher. Thank you.

4:35 So, the `else` is executed when the while finishes. `break` will skip past anything in the `else`, correct? Therefore, if there's no break statement in the while loop, then anything in the `else` could be place completely AFTER the entire `while` block -- it will get executed just the same. CORRECT?

[@johnaweiss]

5:18 i believe int's can be printed. I think the problem here is that you tried to CONCAT an int to a string, not that you tried to print an int.

11:56 you don't need to escape the ' print("glad that's over") or print(' another "example" ')

[@DaveGrayTeachesCode]

Sure, but it's not a bad habit to learn as sometimes it is needed and doesn't hurt anything in this case. Reference for escape characters for anyone reading: www.w3schools.com/python/gloss_python_escape_characters.asp

Thank you, Sir.

Welcome!

​@@DaveGrayTeachesCode At 3:50. Next time you need to move a line of code you can do it with -> (ALT + UP or DOWN) arrow keys. Also works if you select a block of code.

"When you use the variable name 'playagain' for both the loop condition and the 'play again' input, declaring the variable with the same name 'playagain,' it is working due to a truthy value. However, is this considered good practice?"

[@miedsekadse7136]

👍

[@PeranMe]

It’s a little unfortunate to reuse the ”playagain” variable as the input destination. It certainly illustrates that the ”continue” statement doesn’t evaluate the ”while” condition, but it might trip up a beginner in a different situation. Regardless, thoroughly enjoying this series, thanks for sharing!

[@DaveGrayTeachesCode]

It appears I have created some confusion because the "continue" statement goes to the next iteration, but before it starts the iteration, the "while" condition is evaluated. As long as "playagain" has a value that is not False, it is considered to be True. Test this out by assigning a string to a variable. Then make an if statement that says if (variablename): print("This is true") ..it will evaluate as true.

[@PeranMe]

@@DaveGrayTeachesCode Aaahhh…. You’re absolutely right, my bad! See, this is why I watch beginner videos too, despite having used Python for more than 11 years now - there’s always something you’ve missed along the way. Again, thanks!
