B. Code Practice – All 23 Questions
Basic Python and User-Defined
Functions
1. Write a Python program that asks any
two numbers and displays the greater one.
2. Write a Python program that asks the
length, breadth, and height of a room. Create a user-defined function to
calculate the area of the floor. Use another function to calculate the volume
of the room.
Hint:
- Area = Length × Breadth
- Volume = Length × Breadth × Height
3. Write a Python program that asks for
the length in feet and converts it to inches.
Hint: 1 foot = 12 inches.
4. Write a Python program that asks
three different numbers and calculates the product and average. Use a function
for product and a subprogram for average.
5. Write a program to calculate the area
of a square using a function. The user should input the side length.
6. Write a program that calculates the
Total Surface Area of a cuboid using a function.
Hint: TSA = 2(lb + bh + hl)
7. Write a Python program to calculate
the perimeter of a square using a subprogram.
Hint: Perimeter = 4 × L
8. Write a Python program to calculate
the circumference of a circle using a subprogram.
Hint: Circumference = 2Ï€r
9. Write a program to calculate the
total surface area of a sphere using a subprogram.
Hint: TSA = 4Ï€r²
10. Write a program to calculate the
curved surface area (CSA) of a cuboid.
Hint: CSA = 2h(l + b)
Series and Mathematical Operations
11. Write a Python program using a
subprogram to generate the series:
2, 3, 5, 8, 13, 21, 34
Generate up to 10 terms and calculate
the sum of the series.
12. Write a Python program to find the
sum of digits of a number using a user-defined function.
Example: If the user enters 123, the
result should be 6.
13. Write a Python program to display
the multiplication table of a number up to 10 using a user-defined function.
14. Write a Python program to find the
factorial of a number using a user-defined function.
Example: 5! = 5 × 4 × 3 × 2 × 1 = 120.
File Handling
15. Write a Python program to create a
file named student.txt and store the name and class of 3 students.
16. Write a Python program to read and
display the content of student.txt.
17. Write a Python program to add
(append) one more student's name and class to the existing file student.txt.
Series and Functions – Additional
Question
18. Write a Python program to generate
this series using a function:
2, 3, 5, 8, 13, 21, 34
Generate up to 10 terms and also
calculate and display the sum of the series.
Functions and Arithmetic Operations
19. Write a Python program to input two
numbers and calculate:
- Sum
- Product
- Difference
Use three separate functions for each
calculation.
Pandas and CSV File Handling
20. A file named employee.csv stores
Name, Address, Gender, and Salary.
Write a Python program to show the
records of employees who earn more than 75,000.
21. A file named result.csv stores data
with columns:
Symbol No, Name, Gender, English,
Nepali, Maths, Computer
Write a Python program to display the
records of students:
- Whose gender is 'M'
- Who scored more than 85 in Computer.
22. A file named employee.csv contains
data with fields:
Name, Address, Gender, Salary
Write a Python program to display the
data of employees with salary more than 50,000.
23. A file named record.csv contains
columns:
Roll No, Name, Gender, English, Nepali,
Maths, Computer
Write a Python program to display the
records of students:
- Whose gender is 'F'
- Who scored more than 90 in Computer.
Sample Programs – Questions Only
1. Write a program to take two numbers
as input and print their sum.
2. Write a program to check if a number
is positive, negative, or zero.
3. Write a program to ask for the user's
age and determine if they are an adult or not.
4. Write a Python program to create a
new file and write a message into it.
5. Write a function to calculate the
area of a rectangle.
6. Write a function to check if a number
is even or odd.
7. Write a function to return the square
and cube of a number.
8. Write a program using a for loop to
print numbers from 1 to 10.
9. Write a program using a while loop to
find the sum of the first 10 natural numbers.
10. Write a program to print all even
numbers from 1 to 20 using a for loop.
11. Write a function to calculate simple
interest using a default argument for the rate of interest.
