python - How to remove the left part of a string?

Question

I have some simple python code that searches files for a string e.g. path=c:path, where the c:path part may vary. The current code is:

def find_path(i_file):
    lines = open(i_file).readlines()
    for line in lines:
        if line.startswith("Path="):
            return # what to do here in order to get line content after "Path=" ?

What is a simple way to get the text after Path=?

Answer 1

If the string is fixed you can simply use:

if line.startswith("Path="):
    return line[5:]

which gives you everything from position 5 on in the string (a string is also a sequence so these sequence operators work here, too).

Or you can split the line at the first =:

if "=" in line:
    param, value = line.split("=",1)

Then param is "Path" and value is the rest after the first =.
