You can read and edit all the line doing something like:

file = open('your_file.txt', 'r')
read_file = file.readlines()
file.close()

file1 = open('your_file.txt', 'w')

var = 'filename.txt'

for lec in range(len(read_file)):
    if lec == 1:
        file1.write('' % var)
    else:
        file1.write(read_file[lec])
file1.close()
