- 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
- # for single like quote or """ quote """ for multi line quote
#quote """quote quote"""
- display output
print "Hello World"
- remove character value
- like with regular expression, you can remove a characters normal value by adding \ in front.
'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"
