Python Basics

What does the print() function do?

• Connects to the nearest printer and prints the current file

• Displays the written contents of the entire file

• Displays the output of the code in the function

• Displays the code written in the function

What are the pieces of a for loop?

• Colon; :

• Parenthesis; ()

• Range function; range(int)

• Placeholder variable; count

• While keyword; while

In your own words, explain the problem(s) with this code

x = "Akash"

print("Knock knock)

print("Who's there?")

print("It's " + y)

What are the errors in this code?

Select all that apply.

var1 = "A"

2nd_var = "B#"

if var1 = 2nd_var:

print("Harmony")

else:

print("Discord")

• Nothing is wrong

• Invalid variable name

• Invalid use of special characters in String

• Incorrect Boolean comparison operator

• Incorrect syntax for if statement

What must be added? (Look carefully)

pageCount = 500

if pageCount > 500:

print("This book 500 pages or more!")

else:

print("Find a longer book.")

• Add an equal sign to the greater than sign

• Add the str() function to 500 in the print statement

• Add parenthesis to the if statement

• Another ! to the first print statement

What do the str(), int(), and float() functions have in common? Select all that apply.

(Hint: These functions can "convert" their own types too)

• All can properly convert '16' without error

• All convert any value to a specified data type

• All can convert each other's types always

• All can properly use '42.5' without error

• All convert one data type to another

Find the problem

counter = 0

while counter < 10:

print(counter + 1)

• Missing parenthesis from while function

• counter variable never increases

• Operation within print function

• Missing quotation marks from print function

What is the main reason one would use a while loop over a for loop?

• While is faster because it loops on its own without a Boolean expression

• While can be used when the end of the loop is unknown

• While ends whenever the Boolean expression is False

• While can create infinite loops which can throw an error

What did you think about using Quizizz and this quiz style?

• I thought it was great!

• I liked it.

• It was ok...

• I think we should use something else (etc. Kahoot?)

• Yeah... I'll pass on these.
