This short tutorial explains how to password protect a Word document in Python. It provides the details about the configuration of the development environment, a step-by-step process to write the application, and a runnable sample code to demonstrate the document protection in Python. It will also provide the options to protect the Word files like DOCX, DOC, etc. in different ways.

Steps to Protect Word Document in Python

1. Establish the environment for using Aspose.Words for Python via .NET to add password
2. Create an empty or load an existing Word file using the Document class object for locking with a password
3. Call the protect() method for locking the document
4. Provide the desired protection type and password in the protect() method
5. Save the resultant Word file having desired protection

The above steps describe the process to protect document with password in Python in an organized way where first the source link is provided that guides to establishing the development and testing environment. Once the environment is set, you may create a new Word file or load an existing Word file by providing the file name in the Document class constructor. This Document class contains all the methods and properties that are required to set the protection type and password to protect the file.

Code to Add Password to Word Document in Python

This code demonstrates how to lock a Word document in Python by sharing the important namespaces, classes, methods, and properties like we protect the source Word file by providing the protection type ALLOW_ONLY_COMMENTS, however, you may use other options also like READ_ONLY for all types of restrictions, ALLOW_ONLY_REVISIONS for allowing the revision marks, and ALLOW_ONLY_FORM_FIELDS for editing of the form fields only.
