Python Create File (Empty Text File) | Create file if not exist

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?

You will need to use a python in the build method (function) Open to get a file object and create the file. The file object has a function and attributes to write and read etc.

Syntax:

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")

Modes

  • w write mode (if the file doesn’t exist create it and open it in write mode)
  • r read mode
  • a append 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")

Output : 

Python Create File (Empty Text File) output

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")

Output :

example creating pdf and images files output

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 os.path.exists function:

import os.path
os.path.exists(file_path)

It will returnTrue for both files or directories but you can instead use if the file is specified.

os.path.isfile(file_path)

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

  1. import os.path

    filePath = “c://Python_Tools//List.txt”
    with open (filePath, “r”) as myfile:
    data = myfile.readlines()
    for line in data:
    fn = str(data) + “.txt”
    f = open(fn, “w”)

    is not working.

  2. it’s not working.
