So to store a name we would use:
name =
input
(
"What is your name ? --> "
)
Slide 16 - Slide
filmpref = input("What kind of films do you like? ")
Label the correct parts of the code with the symbols.
Click the icon for more information
This the the variable name given to a piece of information
This will allow the user to enter information that will be saved to the variable.
This is a string, we place a question inside so the user knows which information to enter.
