Most of this will come down to reading [PEP8][0], however I'll state them here anyway.

 - `if` statements don't need parentheses, so don't put them around them.  You seem to go between doing this and not, remember to also be consistent

 - Functions at module level should have two new lines between them and other things, rather than one as you have now

 - In your function calls, you have unexpected spaces around keyword/parameter assignments

 - There should also be two blank lines between the `import` statements and other code

 - You should have at least two spaces before inline comment.

 - Many of your lines are too long, they should only be 79 characters maximum

 - In [*Whitespace in Expressions and Statements*][1],

 > Avoid extraneous whitespace in the following situations:
 >
 > ...
 >
 > Immediately before a comma, semicolon, or colon:
 > 
 >     Yes: if x == 4: print x, y; x, y = y, x
 >     No:  if x == 4 : print x , y ; x , y = y , x 

 - You shouldn't have multiple statements on one line (there should be a newline after the colon)

 - There is no newline at end of file as seen here.
