Mail Merge
Mail merge is a process used to create multiple personalized documents, such as letters, emails, or labels, from a template and a data source containing variable information.
Initially, we create a document template using software like Microsoft Word or Google Docs. This template contains the fixed text or content that remains the same across all the documents. However, certain parts of the document, such as recipient names, addresses, or other variable information, are left blank or marked as placeholders. In the same manner, we are going to use Python Program to merge two files so that we can generate our own mail merge functionalities. So, this blog will help us how to create a mail merge program using python.

Creation of Files
First of all, we need to create at least two files so that we can merge them together. Let us say, we already created a file with the filename Students.txt which includes all the names of the students of a school. Also, we created a file with the filename Data.txt which includes all the details to be sent for a notice to the students.
Now, we are required to send the same notice to all the students. In order to do so, we open the Students file with the open() function opening it in read mode, and assigns the file Objects(file contents) to a variable. We can give the variable name as we want.

with open("Students.txt", "r") as variable_name

with open("Info.txt", "r") as variable_name

# Mail Merge Program

with open("Users.txt", "r") as Users:
    with open("Info.txt", "r") as Body:
        info = Body.read()

        for user in Users:
            msg = "Greetings " + user + " " + info # Greetings Tomba Hello!!

            with open(user.strip() + ".txt", "w") as Mail:
                Mail.write(msg)
