IndentationError: unexpected indent

[metulburr]

I would probably not call a variable in_something for that reason alone

Error:
  File "tester.py", line 7
    if item in_stock:
                   ^
SyntaxError: invalid syntax

Although you are allowed to name a variable anything in python, we prefer to restrict certain ones... such as no built-in's or single char names , CamelCase class names, capped GLOBALS, etc. I would probably add to the list things like in_var as when you read a if header, it suppose to be English readable

if item in in_stock:

and a double in is not readable as well as obviously causing syntax bugs

Im not sure why you got an indentation error. I would also never mix tabs and spaces. Convert all copied code to 4 spaces as that is the norm.

Also use the format instead of concatenation
