findString = "Line 3"
  
# python find string in text file and print line
with open('example.txt') as f:
    lines = f.readlines()
    for line in lines:
          
        if line.find(findString) != -1:
            print('String Found in Line Number:', lines.index(line) + 1)
            print('Line Content:', line)
