PYTHON DAY 12 – ERROR HANDLING, FILE HANDLING & FUNCTIONS
In this lecture we learn how Python handles errors, how programs interact with files, and how functions help organize reusable code.
Topics covered in this session:
ERROR HANDLING
• try block
• except block
• else block
• finally block
• handling runtime errors safely
FILE HANDLING
• open() function
• read() and write() operations
• seek() method
• closing files properly
FILE MODES
• r – read
• w – write
• a – append
• r+ – read + write
• w+ – write + read
FUNCTIONS
• defining functions using def
• returning values using return
• nested functions
• arbitrary arguments (**kwargs)
These concepts are essential for building real Python programs.
This is Day 12 of the Python Made Simple Series.
