Application

File Header

#!/usr/bin/python

Comments

These begin with the # character

Subroutines

These must be placed at the top, under the file header and library includes

def functionname(value):
	#do something
	return somevariable

Variables

There is no method to define a variable type, it is determined by the type of the first value it gets set to
a = 42 will create an int called a with value 42

Loops

Infinite

while True:
	#code to loop

While (check then run)

a = 0
while a < 10:
	a += 1

While (run then check)

while True:
    #code
    if i == 10:
       break	#this exits the while loop

For

for i in range(127,-1,-1):	#step from 127 to 0 by 1
	print i

Conditionals

Equal

if i == 10:
	print i

Not equal

if i != 10:
	print i

Greater than

if i > 10:
	print i

Less than

if i < 10:
	print i

Greater than or equal to

if i >= 10:
	print i

Less than or equal to

if i <= 10:
	print i

If Else

if i == 10:
	print i
else:
 	print "I isn't 10"

Math

a = b + 2	#addition
a = b - 2	#subtraction
a = b * 2	#multiplication
a = b / 2	#division
a = b >> 2	#shift the bits of an int right by an amount of times (2 in this case)
a = b << 2	#shift the bits of an int left by an amount of times (2 in this case)
