Flip comparison

Sourcery refactoring id: flip-comparison

Description:

Moves variables from the right side to the left side of comparisons

Before:

if 1 == x:
    do_x()

After:

if x == 1:
    do_x()

Explanation:

It is a coding convention that when doing comparisons to a numeric constant, the number should be on the right and the variable on the left. Having things be consistent in this way makes the code easier to read.
