Binary files in Python can look scary, but they’re really just files that don’t store plain text. In this video, we cover all basic operations possible on Python binary files in a clear and structured way.
🔹 Topics covered in this video:
• How are binary files used in Python
• Opening binary files using rb, wb, ab
• Writing data to binary files using pickle
• Reading binary files using pickle.load()
• Appending records to a binary file
• Searching and updating records in a binary file
• Deletion of records in a binary file
This video is especially useful for the CBSE Class 12 Computer Science students, board preparation, and beginners learning Python file handling.
If binary files ever felt confusing, this video fixes that.
Code of the operations covered in the video is given below:
#binary file options
#add,view,search,delete,update records
#student: roll, name, marks
