• Types of Functions:
  • Built-in functions: print(), len(), type(), abs(), pow(), round(), min(), max(), sum().
  • User-defined functions.
• Creating User-Defined Functions:

  • Positional arguments.
  • Default arguments.
  • Keyword arguments.
• Returning Values: The return statement.

B. Typographical Errors

Every edition tends to have a few printing mistakes (missing indentation in code, typos in SQL queries). This is a long-standing complaint against Dhanpat Rai publications. Solution: Cross-check code with a teacher or online compiler. sumita arora ip book class 11

Part 4: The Turnaround

Three weeks later, the class had a practical test. The task: "Create a Python program that takes a list of numbers and prints only the even ones."

While others frantically searched their memory or peeked at neighbors, Rohan calmly wrote: Title: The Blue Book and the Broken Code Characters:

numbers = [23, 45, 66, 78, 91]
for num in numbers:
    if num % 2 == 0:
        print(num)

The teacher asked, "How did you remember the modulo operator so quickly?"

Rohan smiled. "Chapter 4, Topic: Arithmetic Operators. There's a blue box that says—'Remember: % gives remainder, not percentage.' I never forgot." Rohan: A Class 11 student who loves gaming
