[Solved] How can I use python to add index numbers for the data saved in the text file [duplicate]

by


You are looking for the enumerate function: https://docs.python.org/2/library/functions.html#enumerate

For instance:

 with open("newfile.txt", "w") as output:
    for index, line in enumerate(open("myfile.txt")):
        output.write("%d %s" % (index + 1, value))
