Integers - Numbers that can be written without a fractional component. 10 and -10 are both integers.
>>> int(4.5)   # Convert a float to integer
4
>>> int(-4.7)    # Integers always round towards zero
-4
>>> int("450")   # convert string to integer
450

Float - Floating point numbers or number with a fractional component. 10.0 and -10.0 are both floats.
>>> float(6)    # Convert integer to float
6.0
>>> float("14.123")    # convert string to float
14.123
>>> 2e4    # Floats can use the letter e for scientific notation - 2x10^4
20000.0
>>> float("nan")    # special float variable 'Not A Number'
nan
>>> float("inf")    # represents positive infinity
inf
>>> float("-inf")    # represents negative infinity
-inf
>>> 7.0 * 2    # Calculations between int and float will result in a float
14.0

Str - Strings

None - No value or Null

Bool - True or False
