python create file if not exists – How to Create File If Not Exists in Python?

python create file if not exists Using the open() Function and Using the touch() Method of the pathlib Module Example with demo. Using a Write mode “w” or “w+” will create a file if not exists in Python.

python create file if not exists

Create a File if Not Exists in Python – Check if File Exists. Check if File Exists using the os.path Module, using the pathlib Module. To create a file if not exists in Python, use the open() function.

Mode	Description
w	Write
r	Read
a	Append
w+	Create the file if it does not exist and then open it in write
r+	Open the file in the read and write
a+	Create the file if it does not exist and then open it in append

file = open('myfolder/pakainfodoc.txt','a+')

file = open('myfolder/pakainfodoc.txt','w+')

Python Create File if Not Exists Using the touch() Method of the pathlib Module

Example

from pathlib import Path

pakainfodoc = Path('myfolder/pakainfodoc.txt')
pakainfodoc.touch(exist_ok=True)
f = open(pakainfodoc)

    if(not fileExist):
        makeFreshFile(baseurl)

    checkFileStatusByOSAccess(baseurl)

Check if File Exists using the pathlib Module

Example : python create file if not exists

from pathlib import Path

if Path('pakainfo_v1.txt').is_file():
    print ("File exist")
else:
    print ("File not exist")
