compressed list python code example

Example 1: python list comprehension

#example: removing common elements found in `a` from `b`.
a = [1,2,3,4,5]
b = [5,6,7,8,9]
# desired output: [1,2,3,4]

# gets each item found in `a` AND not in `b`
print([i for i in a if i not in b])

Example 2: x for x in python

# This could be said as:
x for x in thing: 
# Or
for x in thing:
    return x # Or whatever that puts x in some variable

# Same thing, just really dodgy syntax.
