How To Write A Letter In Python

In this tutorial, we will learn how to write a letter in Python. This is a basic task that is helpful for understanding basic file operations and formatting concepts in Python. By the end of this tutorial, you will know how to create, format, and save a text file containing a letter using Python.

Step 1: Set Up The Letter Template

First, let’s create a function that will generate the letter template. A letter typically has a recipient, sender, message, and date. So we will create a function that has these parameters and returns the formatted letter as a string.

Step 2: Define The Letter Content

Now let’s define a letter’s content by providing values for the recipient, sender, date, and message.

Step 3: Write The Letter To A File

Now that we’ve set up the letter template and defined the letter content, we can write the letter to a text file. To do this, we will use the open function with the “w” (write) mode, which creates a new file if it doesn’t exist, or overwrites an existing file with the same name.

Call this function by providing the letter template and a file name.

Now, you will have a text file called “letter.txt” containing the formatted letter.
