Removing a specific character from a text file

Question

I'm new to Python and coding generally, and I was doing a tiny project and I'm facing a problem:

44, 1, 6
23, 2, 7
49, 2, 3
53, 2, 1
68, 1, 6
71, 2, 7

I just need to remove the 3rd and the 6th character from each line, or more specifically the "," characters from the whole file.

and i need to do it using my python code

for line in my_file:
       ??????????????

Anything helps, thanks.

This is not a code-writing service, and there are probably thousands of questions on how to modify text files in Python already on StackOverflow... — juanpa.arrivillaga, Mar 20 '17 at 19:15
`[''.join(c for c in line if c != '.') for line in my_file]` — blacksite, Mar 20 '17 at 19:15
i'm working on a book cipher decoder, but i just needed that particular step because i wrote the whole thing and i got stuck with it, and i couldn't find it on stackoverflow for python — user7451333, Mar 20 '17 at 19:21
Right, well, this is *still* not an on-topic question. Again, **this is not a code-writing service**. Please see [how to ask](http://stackoverflow.com/help/how-to-ask) — juanpa.arrivillaga, Mar 20 '17 at 19:22

You can replace the character

with open(r'c:\input.txt', 'r') as infile,
     open(r'c:\output.txt', 'w') as outfile:
    data = infile.read()
    data = data.replace(",", "")
    outfile.write(data)

I wish instead of down voting and editing my answer you could have given solution – iamdeowanshi Mar 20 '17 at 19:21
I didn't downvote... others did that. I also rolled back the edit when I realised I was wrong – Aaron Mar 20 '17 at 19:22
