To open a file in python

with --> This handles errors and manages external resources. open --> It is a pyhton funtion used to open a file.

To read a file we can use below format

  with open("login_attrmpt.txt","r") as file:
      file_text=file.read()
  print(file_text)

What is (if name == "main":)

This plays a huge role in the reusability of the code. it ensure that certain code runs only when the file is executed directly, not when it’s imported as a module into another script.

EX: file: math_utils.py

  def add(a, b):
      return a + b
  
  if __name__ == "__main__":
      print(add(2, 3))  # Runs only if you run math_utils.py directly

if we import the file, the print part will not be executed

  import math_utils
