10 Ways to Create Files in Python

Last Modified : Sunday, Aug 18, 2024

In this blog, we'll explore ten different ways to create files in Python. Each method demonstrates a different approach to file creation in Python.

1. Using `open()`

with open("file1.txt", "w") as file:
    file.write("Hello, World!")

The most common way to create a file.

from pathlib import Path

Path("file2.txt").touch()

A pathlib method that creates an empty file if it doesn't exist.

import os

fd = os.open("file3.txt", os.O_WRONLY | os.O_CREAT)
os.close(fd)

Creates a file using low-level OS commands.

import tempfile

with tempfile.NamedTemporaryFile(delete=False) as temp_file:
    temp_file.write(b"Temporary Content")

Creates a temporary file that can be used during program execution.

from pathlib import Path

Path("file5.txt").write_text("This is a file created by Path!")

Creates and writes text to the file directly using pathlib.

import subprocess

subprocess.run(["touch", "file6.txt"])

Uses shell commands to create a file from within Python.

from io import StringIO

sio = StringIO()
sio.write("StringIO file content")
with open("file7.txt", "w") as f:
    f.write(sio.getvalue())

Simulates file-like operations with an in-memory file.

import pandas as pd

df = pd.DataFrame({"A": [1, 2, 3]})
df.to_csv("file8.csv", index=False)

Creates a CSV file from a pandas DataFrame.

import json

data = {"name": "Alice", "age": 30}
with open("file9.json", "w") as json_file:
    json.dump(data, json_file)

Creates a JSON file by dumping Python data structures.

import gzip

with gzip.open("file10.txt.gz", "wt") as gz_file:
    gz_file.write("Compressed file content!")

Creates a compressed GZIP file.

These methods showcase the flexibility of Python in handling file creation across various use cases, from simple text files to compressed files.
