Python2:
Integers normal Integers , like 42, 4321 0 as a prefix: Octal number and 0x means Hex number
Long Integer If an integer literal ends with an l or L, it becomes a Python long integer. It can grow as “long” as needed. Since Python 2.2. the letter “l” or “L” is no longer needed, as integers are automatically converted to long integers on overflow. In Python 3: only Integers!
Floating-point numbers numbers like 3.14159 or 17.3e+02
complex numbers e.g. 1.2+3j
Python3:
Integers No long int anymore, but int “contains” long int
