There are a number of ways in which we can take input from stdin in Python. sys.stdininput()fileinput.input()Read Input From stdin in Python using sys.stdin First we need to import sys module. sys.stdin can be used to get input from the command line directly. It used is for standard input. It internally calls the input() method. Furthermore, it, also, automatically adds '\n' after each sentence. Example: Taking input using sys.stdin in a for-loop Python3 import sys for line in sys.stdin: if 'q' == line.rstrip(): break print(f'Input : {line}') print("Exit") Output Read Input From stdin in Python using input() The input() can be used to take input from the user while executing the program and also in the middle of the execution. Python3 # this accepts the user's input # and stores in inp inp = input("Type anything") # prints inp print(inp) Output: Read Input From stdin in Python using fileinput.input() If we want to read more than one file at a time, we use fileinput.input(). There are two ways to use fileinput.input(). To use this method, first, we need to import fileinput. Example 1: Reading multiple files by providing file names in fileinput.input() function argument Here, we pass the name of the files as a tuple in the "files" argument. Then we loop over each file to read it. "sample.txt" and "no.txt" are two files present in the same directory as the Python file. Python3 import fileinput with fileinput.input(files=('sample.txt', 'no.txt')) as f: for line in f: print(line) Output: Example 2: Reading multiple files by passing file names from command line using fileinput module Here, we pass the file name as a positional argument in the command line. fileargument parses the argument and reads the file and displays the content of the file. Python3 import fileinput for f in fileinput.input(): print(f) Output: Create Quiz Comment A ayushmankumar7 Follow 10 Improve A ayushmankumar7 Follow 10 Improve Article Tags : Python python-basics python-input-output Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
