Create File If Not Exist in Python

Create File If Not Exist in Python

Python is an interesting language to learn. It is one of the most popular programming languages in the world and has a welcoming development platform. This blog post will explore how to create a file if it doesn’t exist in Python.Sometimes you want to create a file, but it doesn’t exist. This can be caused by the file not being created yet. In this case, you can use the open() function. open is a built-in Python function that opens the file and returns it as a file object. It takes the file path as input and the mode. It returns the file object as output.

from pathlib import Path

fle = Path('data.py')
fle.touch(exist_ok=True)
f = open(fle)

open() in Python does not create a file if it doesn’t exist

In Python, the “open” function is used to open a file, read from the file, write to the file, or perform any other file-related operation. When opening a file, the function takes two values, the file path and the file mode. The mode is optional, but it is important to specify the mode, because some files have different modes. The file mode specifies what kind of operation is to be performed on the file: reading, writing, appending, and more.Sometimes you want to create a file if it doesn’t exist. For example, if you want to store an image on the filesystem, you need to create a file first before you can store the image on it. Here is a tutorial on how to create a file in Python if it doesn’t exist.

import os
if os.path.exists("myfile.dat"):
     f = file("myfile.dat", "r+")
else:
     f = file("myfile.dat", "w")
     print("Create a file successfully")

It’s been said that the function of code is to build a system. So one of the most important things that determines how well a system functions is how well it is able to handle exceptions. One of the most common exceptions in Python is the ‘file not found’ exception. This blog will go over the use of the open() function to handle the file not found exception.While the Python language has built-in functions for most tasks, you might need to create a file if it doesn’t exist. There are a few options available. The open() function, which is a built-in Python function, can be used. The open() function takes the file path and the mode as input and returns the file object as output.

import os
import errno

flags = os.O_CREAT | os.O_EXCL | os.O_WRONLY

try:
    file_handle = os.open('filename', flags)
except OSError as e:
    if e.errno == errno.EEXIST:  # Failed as the file already exists.
        pass
    else:  # Something unexpected went wrong so reraise the exception.
        raise
else:  # No exception, so the file must have been created successfully.
    with os.fdopen(file_handle, 'w') as file_obj:
        # Using `os.fdopen` converts the handle to an object that acts like a
        # regular Python file object, and the `with` context manager means the
        # file will be automatically closed when we're done with it.
        file_obj.write("Look, ma, I'm writing to a new file!")

If you ever find yourself trying to make a file if doesn’t exist in Python, you can use the open() function. The open() is a built-in Python function that opens the file and returns it as a file object. The open() takes the file path and the mode as input and returns the file object as output.Sometimes we need to create a file that doesn’t exist. For example, to create a file called ‘myname.txt’ if it doesn’t already exist. Python offers a function called open() which is helpful in this situation. This blog will take you through the process of creating a file if not exist as well as the function, open()

import os
player = 'bob'

filename = player+'.txt'

if os.path.exists(filename):
    append_write = 'a' # append if already exists
else:
    append_write = 'w' # make a new file if not

highscore = open(filename,append_write)
highscore.write("Username: " + player + '\n')
highscore.close()

Conclusion:

To create a file if not exist in Python, use the open() function. The open() is a built-in Python function that opens the file and returns it as a file object. The open() takes the file path and the mode as input and returns the file object as output.The open() function is used to open a file and return it as a file object. The open() function takes the file path and the mode as input and returns the file object as output. It is important to know how to create files in your Python scripts. The open() function is one of the functions that will help you create files in your Python program. Here is a blog post that will go over how to create a file if it doesn’t exist in Python.
