Answer 1

type-conversion is used to change strings to integers/floats or change floats/integers to strings.

Why use this?

reason 1) to change user input (wich is a string) to numbers.

reason 2) being able to add numbers to strings to didplay them. for instance if you want to display a score.

Hoe to use?
str (number) # makes a string of everything inside ()

int (string or float) # makes integer of everything inside ()

float (str or integer) #makes float of everythin in ()

Answer 2
