for line in infile:
		if(line[len(line)-1:] = "\n"):
			line = line[:len(line)-1]
		output = "Searching for: " + line

Giving me the error:

if(line[len(line)-1:] = "\n"):
SyntaxError: invalid syntax

I'm basically trying to take each line of the file and I want to exclude the newline character at the ends of the lines... at first i just had "line = line[:len(line)-1]" but it was removing the last character from the last line which does not have a newline character at the end


NEVERMIND: I see stupid error... i wasn't comparing, i was assigning with =

Also, Python has a function rstrip() that will do that:
line = line.rstrip('\n')
no need for the if statement.

Thanks for giving us a descriptive title.
BTW, the operation you are talking about is actually called slicing.
