Conditionals

• If statement

• else : stops asking questions and just runs, only used once if “if” statement is false

• elif : Extra conditions, asks another question, can have multiple but stops once the previous ones are false

* For Else and Elif, you must exit the “If block” first

Comparison Operators: <,>, greater than or equal to, or less than or equal to

<, >, <=, >=, or ==

*= means an assignment, like print=

How to use a String

print(“Hello world”)

• Make sure to use ““

• Don’t need to write str

for loops

for item in collection

• they repeat until the number of items in your collection.

• EX. for name in [“Alice”, “bob”, “Charlie”]:

  • print(name)

Range()

• this range starts at 0 and goes up to ,not including, the number inside the parens

Ex. For number in range(3):

• print(number)

Outcome:

0

1

2

Range (#,#)

• When you want to type down numbers in a certain range

• you can do this two ways, one using just one number and adding an amount to the number using f””, or just giving the exact range with (x,x)

EX.

for num in range (7)

• print(f”num +3”)

Output: 3,4,5,6,7,8,9

for num in range (3,9)

• print(num)

Output: 3,4,5,6,7,8,9
