# With is used for better and more readable file handling.
# Instead of having to open and close the file:
file_handler = open('path', 'w') 
file_handler.write('Hello World!') 
file_handler.close() 

# You can use with which will close the file for you at the end of the block:
with open('path', 'w') as file_handler:
  file_handler.write('Hello World!') 

# Another common use is with pickle files:
with open('pickle_path.pkl', 'rb') as file_handler:
  file_contents = pickle.load(file_handler)

# file handling 
  
# 1) without using with statement 
file = open('file_path', 'w') 
file.write('hello world !') 
file.close() 
  
# 2) without using with statement 
file = open('file_path', 'w') 
try: 
    file.write('hello world') 
finally: 
    file.close() 
    
# using with statement
