Learn how to write and append data to files in Python.

Python can create and write to files just as easily as reading them.

Writing to a File

with open("output.txt", "w") as file:
    file.write("Hello, World!\n")
    file.write("Python is great!\n")

with open("log.txt", "a") as file:
    file.write("New log entry\n")

lines = ["Line 1", "Line 2", "Line 3"]
with open("output.txt", "w") as file:
    for line in lines:
        file.write(line + "\n")
