That's some really basic code. Please, in the future, post your code in code tags, like so:



Now, what have YOU tried in terms of running regexes?

I'm pulling in a file and would like to perform acouple regexs' on the txt file. My syntax looks like this.

f = open('Test.txt','r')
for line in f:
    print(line,end=' ')

Which reads and displays my txt file but i can't seem to run any regexs on it. Please help.

Thanks for the comment. I have tried things like
[f{1,}]
Have I created an object out of this statement. [f=open('test.txt','r')] (textfile). To be honest I searched and found a generator I could import my text file to and run statements but have had no luck.
I have a book here "Programming in Python 3" but I find it difficult to apply the examples.What I want to do is serach through a large text file as sys agvr and run regex on it. I also tried to import re which is something I don't know if I have to do?????

Quick example:

import re

# File contents
# Man:test
# Other Man:test
# Man:test
# Other Man:test

# Compile the string to find
# In this case, if the line begins with "Man"
to_find = re.compile('^Man')

# Open the file for reading
with open('c:\sketch.txt', 'r') as f:
    # Read line by line
    for line in f:
        # Try to match compiled regex
        if to_find.match(line):
            # Found it, so print the whole line
            print (line.strip())

Output:

C:\Python31>python re.py
Man:test
Man:test
