I have been trying to replace a word in a text file with a value (say 1), but my outfile is blank.I am new to python (its only been a month since I have been learning it).
My file is relatively large, but I just want to replace a word with the value 1 for now. Here is a segment of what the file looks like:
NAME SECOND_1 ATOM 1 6 0 0 0 # ORB 1 ATOM 2 2 0 12/24 0 # ORB 2 ATOM 3 2 12/24 0 0 # ORB 2 ATOM 4 2 0 0 4/24 # ORB 3 ATOM 5 2 0 0 20/24 # ORB 3 ATOM 6 2 0 0 8/24 # ORB 3 ATOM 7 2 0 0 16/24 # ORB 3 ATOM 8 6 0 0 12/24 # ORB 1 ATOM 9 2 12/24 0 12/24 # ORB 2 ATOM 10 2 0 12/24 12/24 # ORB 2 #1 #2 #3
I want to first replace the word ATOM with the value 1. Next I want to replace #ORB with a space. Here is what I am trying thus far.
input = open('SECOND_orbitsJ22.txt','r') output=open('SECOND_orbitsJ22_out.txt','w') for line in input: word=line.split(',') if(word[0]=='ATOM'): word[0]='1' output.write(','.join(word))
Can anyone offer any suggestions or help? Thanks so much.

Answer
Use replace
.
line.replace("ATOM", "1").replace("# ORB", " ")
Untested code:
input = open('inp.txt', 'r') output = open('out.txt', 'w') clean = input.read().replace("ATOM", "1").replace("# ORB", " ") output.write(clean)
