04. Python File Handling | tell() & seek() + Binary File Modes | rb, wb, ab, rb+, wb+, ab+, xb

Learn Python File Handling with File Pointers, tell(), seek() and Binary File Handling in this fourth episode of the series. In this video, we move beyond basic text file operations and understand how Python tracks the current position inside a file and how we can move that position using seek(). We also dive into Binary File Handling and learn important binary file modes used for working with files such as images, audio, video, PDFs, and other binary data. 📚 Topics Covered 🔹 What is a File Pointer? 🔹 tell() – Find the current file position 🔹 seek() – Move the file pointer 🔹 Understanding file pointer movement 🔹 Reading data from a specific position 🔹 What are Binary Files? 🔹 Text Files vs Binary Files 🔹 Binary File Modes 🔹 rb – Read Binary 🔹 wb – Write Binary 🔹 ab – Append Binary 🔹 rb+ – Read + Write Binary 🔹 wb+ – Write + Read Binary 🔹 ab+ – Append + Read Binary 🔹 xb – Create Binary 🔹 xb+ – Create Binary + Read/Write 🔹 Practical examples 🔹 Important rules and differences 🔹 When to use each binary mode ⏱️ Chapters / Timestamps 00:00 – Introduction & Recap of Text Modes 01:05 – File Pointer: tell() & seek() 01:21 – tell() – Check Current Position 02:38 – seek() – Move File Pointer 03:20 – tell() Code Demonstration 07:07 – Reset Pointer with seek(0) 09:25 – tell() vs seek() Summary 10:15 – Introduction to Binary Files 11:13 – Binary File Modes Overview 11:53 – rb Mode – Read Binary 13:57 – rb Practical Example & Missing Files 16:01 – wb Mode – Write Binary 16:55 – wb Example & Overwriting 18:45 – ab Mode – Append Binary 19:33 – ab Practical Example 22:25 – rb+ – Read & Write Binary 25:27 – wb+ – Write & Read Binary 28:20 – xb – Exclusive Binary Creation 30:48 – Complete Binary Modes Revision 33:40 – Conclusion & Upcoming Topics 🎯 Who Should Watch?
