variables

variables can be integers, floats, or boolean. Integers are whole numbers, floats are numbers with remainders, boolean is either True of False.

variable=integer

arithmetic operators

add/subtract/multiply/divide/exponentiation/modulo

exponentiation (exponential, similar to square roots)

2 ** 3=8   (2*2*2)

modulo (remainder)

5 % 2=1  (5/2 = 2 with a remainder of 1)

comments

print

display output

print "Hello World"

remove character value

like with regular expression, you can remove a characters normal value by adding \ in front, however this does not work with all characters in python

'Help! Help! I\'m being repressed!'

string methods

len() ; lower() ; upper() ; str()

len() = get length of string - applies to anything within the parentheses

len(length)   =   6

lower() = convert to lowercase - applies to only the value after the .

LOWERCASE.lower()   =   lowercase

upper() = convert to uppercase - applies to only the value after the .

uppercase.upper()   =   UPPERCASE

str() = convert to string - applies to anything within the parentheses

str(3.14)   =   "3.14"

user input

variable = raw_input("display message")

name=raw_input("display message")

Comparators

==, !=, <, <=, >, or >=
