File Handling in Python - Basic Concept

File (Flat) Handling in Python

Types of files in python:

1: Text file: Stores data in the form of characters. Customarily used to store text/string data.

2: Binary file: Stores data in the form of bytes. It can be used to store text, images, audio and video.

Open() Function:

To open a file, we use the open() function. Here we need to mention 'filename' and 'mode' in which we want to open that file.

Syntax: File Handler = open("FileName", "Mode")

Mode: w (write), r(read), a(append) etc.

A file that is opened should be closed with the help of the close() function.

To write in a file, we use the write() function.

Example:

A simple Python program to open, write, read and close a file.

# Open a file in write mode

f = open("myFile.txt","w")

# Take input from user

str = input("Enter text: ")

f.write(str) # Write the string into file

f.close() # Close the file

# Again open the file in read mode

print("Now Reading that file....")

f = open("myFile.txt","r")

str = f.read() # Read from file

# Display the content on the screen

print(str)

f.close() # Close The file

Thank You!
