How to Write Line by Line to a File Using Python

When learning to program, we must know how to work with files. We should know how to read data from a file, how to write data to a file, how to append data to a file, etc. This article will not focus on all the operations we can perform over files but learn how to write to a file line by line using Python.

Write to a File Line by Line Using Python

Suppose we have a bunch of strings that we have to write to a file. To write them line by line, we have to append an end-line character or \n at the end of each line so that the strings appear individually. Refer to the following code for the same.

data = [
    "Hello World!",
    "This is a Python program.",
    "It will write some data to a file.",
    "Line by line.",
]

file = open("file.txt", "w")

for line in data:
    file.write(line + "\n")

file.close()
