A 'with' statement is a compound statement.  It must be followed by a 
'suite', which usually consists of an indented block of statements.
This is line 17 from the first non-blank line you posted.

Please stop spamming the list with multiple posts.  Do spend a few hours 
reading the tutorial until you understand my answer.
https://docs.python.org/3/tutorial/index.html  Also read

so you can ask better questions.

I presume you got "SyntaxError: expected an indented block".
A minimal example getting this error is, for instance,

while True:
a = 1
