<bot>: Here is a Python function to check if a string in a file line is a string

import os

def check_if_string_in_file_line(file_name, string):
  """
  >>> file_name = "test.txt"
  >>> string = "test"
  >>> check_if_string_in_file_line(file_name, string)
  """
  with open(file_name, "r") as f:
    for line in f:
      if string in line:
        return True
  return False

# Enter the file name
file_name = "test.txt"

# Enter the string
string = "test"

# Calling the function
if check_if_string_in_file_line(file_name, string):
  print("String found")
else:
  print("String not found")

#Example Output
# String found
