RE function

ok so now I have the following code, but the output is a set of brackets.

1 2 3 4

import re str = open('directory', 'r').read() pattern = re.findall('\d+(M)\d+(N)\d+(M)', 'filename') print pattern

output

1

First, str is a reserved word. Don't use it as a variable name. Second, the variable should be the second part in findall. 'filename' is a string. It has no connection to anything else. When you are putting it in findall, you are searching the literal text 'filename', not any file you've opened. You want something more like:

1 2 3 4

import re text = open('directory').read() results = re.findall('\d+(M)\d+(N)\d+(M)', text) print results

Oh I got my answer. Thank you.
