File Handling:

All web application are having a important part its called File Handling. Python has several functions for creating,reading,updating, deleting files.

Syntax :

f = open("demofile.txt")

Example :

f = open("demofile.txt", "r") 
print(f.read())

Write to an Existing File:

f = open("demofile.txt", "w") 
f.write("Woops! I have deleted the content!")

Create a New File:

f = open("myfile.txt", "x")

Delete a File using os.remove() function:

import os 
os.remove("demofile.txt")

import os

if os.path.exists("demofile.txt"):

  os.remove("demofile.txt")

else:

  print("The file does not exists")
