Posted under » Python on 3 December 2025

There may be a time when you want to look for a word line by line in a text file. Here is one way

with open(r'email.txt', 'r') as fp:
    lines = fp.readlines()
    for row in lines:
        word = 'gaybo011@'  # String to search for
        if row.find(word) != -1:
            print('String exists in file')
            print('Line Number:', lines.index(row))
