• [x] Reduce time assigned to exercises from 10 to 5 min

[weilu]

Participant questions:

• Is the colab notebook saved on the platform or my own computer?
• Does everything need a unique variable name? What's the best practice?
• Are missing data points covered the same across data types?
• Do x and print(x) spit out the same result?
• So if I understand correctly, you can do any function like +=; i.e., -=, *=, etc.?
• Do you know how can I see which packages are installed on collab by default?
• What would you do if your number is separated by commas like 19,000?
• Is there a function that 'uppers' ONLY the first letter of each word?
• Can I 'append' a list to another?Like the '+' operator for string concat

Wei's feedback:

• hw = 'hello World' consider giving it a better variable name.
• Exercise 2c passed then failed after the participant finished the rest of the exercises due to variable reuse.
• division: consider cover // which will return an integer
• Consider cover f-string in place of .format() and make .format() something just to recognize, as increasingly people are using f-strings and .format are more from legacy code.
• Methods vs function: IIRC function is generic; methods are functions operated on an object, more often used in the land of OOP. Not necessary to introduce OOP, just a note.

This is what I said right? Maybe in more layman terms, but I will favor "understandable to layman" over "the most correct" in this session.

Consider cover f-string in place of .format() and make .format() something just to recognize, as increasingly people are using f-strings and .format are more from legacy code.

I have removed the places I use format in the rest of this session. We should show .format() and I like where I currently show it as it is right after we talk about string methods. And right after we do we introduce f-strings. And I think this agrees with what you say. Or is your comment that we should remove .format() from all other sessions as well?

Added to table of operators in 2457f8d07827264e9118b424b505e4318ee26e60 but did not add more about it

• Exercise 2c passed then failed after the participant finished the rest of the exercises due to variable reuse.

Not sure I follow exactly. But since this exercise is about updating and overwriting variables there is always going to be some order of running the cells that will not pass the assertion. But I think that is also a part of the exercise. To get a felling for how running cells in order or not makes a difference in a notebook context.

Participant questions:

@kbjarkefur's answer in sub bullets. Let me know if anyone of y'all disagree with my conclusions

• Is the colab notebook saved on the platform or my own computer?
  • Added a quick note about this here c1ec4eaf234aa294ace0cfd7b8180a681ab03df6 but this is covered in S3 in more detail.
• Does everything need a unique variable name? What's the best practice?
  • This is covered later. I think it is still better to get to later as it takes a long time in this session before we at all can get started.
• Are missing data points covered the same across data types?
  • I missed this question during the session. I cover the None type. But missing data in a dataset is covered in S3.
• Do x and print(x) spit out the same result?
  • This is covered later.
• So if I understand correctly, you can do any function like +=; i.e., -=, *=, etc.?
  • I added link to the operators web page where += is introduced in 1161d7ba2c3aa2b4114a716fab5fe9ad405e4020
• Do you know how can I see which packages are installed on collab by default?
  • will be covered in S3 and was a very specific question
• What would you do if your number is separated by commas like 19,000?
  • I liked the question as I learned 19_000 notation, but do not think it is used commonly enough for us to include in session
• Is there a function that 'uppers' ONLY the first letter of each word?
  • Covered in an exercise later
• Can I 'append' a list to another? Like the '+' operator for string concat
  • This is covered later, participant beat me to this point - hence, wont address
