fileinput.input() in Python Last Updated : 29 Dec, 2023 Comments Improve Suggest changes Like Article Like Report With the help of fileinput.input() method, we can get the file as input and can be used to update and append the data in the file by using fileinput.input() method. Python fileinput.input() Syntax Syntax : fileinput.input(files) Parameter : fileinput module in Python has input() for reading from multiple files.input() in fileinput reads input from various sources.files parameter specifies file names, defaulting to stdin if not specified.Return : Return the data of the file. What is fileinput.input() in Python?`fileinput.input()` in Python is a function provided by the `fileinput` module. It allows reading input from multiple files. The function returns an iterable, and the optional `files` parameter specifies the files to read from; if not provided, it defaults to reading from standard input (stdin). Each iteration of the iterable corresponds to a line from the specified files. Python fileinput.input() Examples There are various methods to open a file by user input in Python here, we are discussing some general use cases of opening a file by user input in Python which are the following. Reading From a Single File Input File In this example we can see that by using fileinput.input() method, we are able to get the data of the file line by line by using this method. Python3 import fileinput filename = 'example.txt' for line in fileinput.input(files=filename): print(line, end='') Output : Reading From Multiple FilesInput Files In this example code utilizes the fileinput module in Python to read input from the specified files, 'gfg.txt' and 'gfg1.txt'. The fileinput.input() method returns an iterable, and the loop iterates over each line from the files, printing them to the console Python3 # import fileinput import fileinput # Using fileinput.input() method for line in fileinput.input(files =('gfg.txt', 'gfg1.txt')): print(line) Output Comment More infoAdvertise with us Next Article fileinput.input() in Python J Jitender_1998 Follow Improve Article Tags : Python Python fileinput-library Practice Tags : python Similar Reads fileinput.filename() in Python With the help of fileinput.filename() method, we can get the last used file name which we have used so far by using fileinput.filename() method. Syntax : fileinput.filename() Return : Return the last used file name. Example #1 : In this example we can see that by using fileinput.filename() method, w 1 min read fileinput.isfirstline() in Python With the help of fileinput.isfirstline() method, we can get the boolean value as True if line read from the file is very first line else false by using fileinput.isfirstline() method. Syntax : fileinput.isfirstline() Return : Return True if line read is first line of that file.
