The line: os. With this word, the file is opened and closed immediately after leaving the scope. Two print functions print whether the file is closed or not. The first print is inside the scope, so it prints False as the file is not closed, in the next print, the code is out of the scope, so the function prints True. There are two print functions at the end of the code to check whether the file object is opened before using the close function, and closed after that.
When you run the code, you can see that it works well; it appends data to the file and closes the stream at the end. By opening the file for appending and reading, we can use the seek function to enter the position of the pointer as a parameter. This value represents the number of places that the pointer moves to the right.
If you run the code, the two first characters are missing from the first line indexing starts from 0. We will create an application using Python Tkinter that will generate a word document with dynamic values.
Recently, we got a requirement to generate an experience certificate for employees who are leaving the organization using Python Tkinter. Then when the user will fill the form and click on Generate Word button, it will create an experience certificate word document with the dynamic values provided by the user.

It is a popular and easy-to-use python module that can help you convert your command-line-based application into an interactive GUI-based program. We have a dedicated tutorial on our website for learning Python Tkinter with Examples. In this section, we will discuss all the python Tkinter widgets that we have used in creating the Tkinter application for generating experience certificate word files.
Python-docx module allows us to create word document s using python Tkinter. This is a powerful python module that allows the creation of a new word document or updating the existing ones. Using the python-docx module we can work with all those features. Below is the picture of a word document with marked features. Moving forward, we will discuss common methods of a python-docx module using which you can create a sample word document in python.
If you want to save time from manually formatting each row of a word document then you can apply a bundle of pre-formatted styles using this feature in a python-docx module. This example, demonstrate how to create style in the python docx module also shows how to use the style on a paragraph in the python docx module. Heading specifies the short description of the topic or content. A good heading is always short and self-explanatory.
In this section, we will learn how to add heading using python. The paragraph is the widely used method as this will require every time you want to add text on the word document using python module python-docx. The below picture shows the column available for uploading images on a word document.
Height and width are optional to provide but it will be either in Inches or cm centimeter. The below example, demonstrate use of docx. In this article, we will discuss how to append text or new lines to an existing file using python.
Whereas, if the file already exists then it opens it. In both cases, it returns a file object, and it has write cursor, which points to the end of the opened file. Now, if you write anything to the file using this file object, then it will be appended to the end. As cursor was pointing to the end of the file in the file object, therefore when we passed the string in write function, it appended it at the end of the file.
We can open the file in append access mode i. For example, Open a file with access mode 'a' with open "sample. In both the above examples, the text gets added at the end of the file. But as we can see, it is not appended as a new line. There might be scenarios when we want to add data to a file as a new line.
