Data types: There are two major categories

• Numbers  (3.25, 77, 88.0)

• Strings ( "hello", "name", " 1 + 3")

• Other categories :

• Functions

• List

"Strings" 

• Lets the user type in letters, numbers and words

• Not used for calculations

• When doing calculations: be sure to check that your value is a number, not a string

str

• The str function tells python to handle the value in the () as a string, not as a number

Floats

• .A floating point value is represented either as whole plus fractional digits (like decimal values) or as a mantissa plus an exponent.
