How to use findall to find keywords in file

[Billy Green]

I'm new to python and was trying to write a (re.findall) code to find stings containing a certain keyword in my file.

This is the code I'm using and I'm getting error messages??? Please help..

q6=open('file1. txt','r')
>>> lines=q6.readli nes()
>>> for i in lines:
... element = re.findall('[^\+\n]+' i),,,,,error message
if element[2]=='chr22'

You left out the comma between the pattern and string arguments.
