Looking for solutions on writing to a file? We have curated this guide with a tutorial in Python write to file with examples. This should be solution to your problem.
Python, as well all know is one of the world’s most popular and growing programming language. Well, the simple reason is due to its scalability and easy application.
But what makes it so easy, that it is used in almost every other field? The reason is the functions in Python.
The Python programming language has a large variety of functions that can be used directly in making programs, software, or even websites.
If you go back to programming languages like C++ or Java, then you might need to write chunks of code to complete a task. But Python provides a single word function for that same task.
Also, the thing that makes Python so popular is the number of ways in which you can perform an operation.
For example, you can also create a function using the lambda function method in Python.

So, today we will be discussing the operation of writing a text into a file in Python. We will see the different ways in which we can write the text to a file in Python programming language.
But before that let us first understand why do we need to write a text in a file.
Why write to a file?
If you are from a computer science background, then you might be aware of the fact that data is stored in memory.
So, when you execute a program, the data gets stored in the RAM, which is a temporary memory. This means that, once the computer gets turned off, the data will also get cleared.
This is where you require to write the data in a file. This process of manipulating the data in a file is also known as file handling.
In file handling you can, write a data into a file and store that file permanently on your laptop. The data that you have written in the file can also be read by using the respective function for it.
Apart, from keeping the data safe from getting cleared, File handling is also required when you have some data that will be needed again and again.
How to use file handling?
Now, let’s see how we can use file handling in Python. For example, if you had made a program in which a user can come and enter their name.
In the program, you can also search for the name of a person. Well, how will it happen?
The name that the user will enter, will be stored in a file on the system, and when the admin searches for the name, the program will crawl in that file and give the result.
Well, this is the theory, now let’s dive straight into the practical coding.

Ways to write in a file
Before, writing the content in a file, you have to first create an object. Using this object you will first open the file in which you will write the data.
In this case, we have created an object name File_object and opened a file, called myfile.txt in writing mode.
File_object = open(“myfile.txt”,”w”)
In Python, you have two simple functions, with which you can easily write the data in a file.
1. write() : Consider a string Str1. Now if you pass this string “Str1” as a variable in this write function then, this function will insert the string “Str1” in a single line in the file.
File_object.write(Str1)
2. writelines() : If you have a list of lines, then you can use this function to write all the lines together in a file.
File_object.writelines(List_name) for List_name = [Str1, Str2, Str3]
