Creating a file in python is very easy. With python inbuilt function you can create a text file, PDF file, images file (jpeg, png..), etc. In this tutorial, you will learn the basics of creating files and functions with examples. To Python Create File you must rely on the built-in open() function where the Open function is an inbuilt method.
How to Python Create File?
Where file_obj is a variable to hold the file object. The mode argument is required ‘w’ because the default value of ‘r’ will be assumed if it is omitted. Where ‘w ‘value stands for write mode.
You have to use any one of mode form w, a, w+ and a+ to create a file.
#create file file_obj = open("filename", "mode")
wwrite mode (if the file doesn’t exist create it and open it in write mode)
aappend mode (if the file doesn’t exist create it and open it in append mode)
w+create a file – if it doesn’t exist and open it in write mode
r+open an existing file in read+write mode
a+create a file – if it doesn’t exist and open it in append mode
Python Create a text file example
We are using w mode to create a file and writing a text in the file.
f = open("cFile.txt", "w") f.write(" Created file")
Creating more files
In this example, we are creating pdf and image files.
pf = open("picFile.png", "w") jf = open("imgFile.jpg", "w") pdff = open("pdfFile.pdf", "w")
QA: How to Python check if the file exists and Create if the file not there?
Its simple question can ask in an interview “How python creates a file if not exists“?
You can do it with
import os.path os.path.exists(file_path)
It will return
True for both files or directories but you can instead use if the file is specified.
Using a Write mode “w” or “w+” will create a file if not exists in Python.
Or use this code first check file exists or not, then do create it.
import os.path file_exists = os.path.isfile(filename) if file_exists: # do something else: # do something else
