Aim - Write a Python program to calculate the gross salary of an employee
Source Code -
print("SALARY PROGRAM")
name= str(input("Enter name of
employee:"))
basic=float(input("Enter Basic Salary
:"))
da=float(basic*0.70)
hra=float(basic*0.10)
ta=float(basic*0.30)
grosspay=float(basic+da+hra+ta)
print("\n\n")
print(" NAME OF EMPLOYEE : ",name)
print(" BASIC SALARY : ",basic)
print(" DEARNESS ALLOW. : ",da)
print(" HOUSE RENT ALLOW.: ",hra)
print(" TRAVEL ALLOW. : ",ta)
print(" GROSS PAYMENT : ",grosspay)
Source Code -
task = ['cleaning', 'cycling']
# Add elements to the list
task_add = ['studying', 'playing', 'gym']
task.extend(task_add)
print("Add:", task)
# Remove an element from the list
task.remove('playing')
print("Remove:", task)
# Update the item at index 1
task[1] = 'running'
print("Update:", task)
# Sort elements based on length
task.sort(key=len)
print("Sort:", task)
Aim - Create a Python code to demonstrate the use of sets and perform set operations (union, intersection, difference) to manage student enrollments in multiple courses / appearing for multiple entrance exams like CET, JEE, NEET etc.
Source Code -
# Example enrollment sets
cet_students = {"Alice", "Bob", "Charlie", "David"}
jee_students = {"Bob", "Eve", "Frank", "Charlie"}
neet_students = {"Alice", "Eve", "Grace", "Charlie"}
#Perform Union Operation
all_students = (cet_students).union(jee_students).union(neet_students)
print("Union (All Students):", all_students)
#Perform Intersection Operation
common_students = (cet_students).intersection(jee_students).intersection(neet_students)
print("Intersection (Common Students):", common_students)
# Perform difference operations
diff_cet = cet_students.difference(jee_students.union(neet_students))
diff_jee = jee_students.difference(cet_students.union(neet_students))
diff_neet = neet_students.difference(cet_students.union(jee_students))
print("Students for to CET:", diff_cet)
print("Students for to JEE:", diff_jee)
print("Students for to NEET:", diff_neet)
Aim - Develop a Python program that takes a numerical input and identifies whether it is even or odd, utilizing conditional statements and loops.
Source Code -
def check_even_odd():
while True:
try:
num = int(input("Enter a number (or type '0' to exit): "))
if num == 0:
print("Exiting the program. Goodbye!")
break
elif num % 2 == 0:
print(f"{num} is an even number.")
else:
print(f"{num} is an odd number.")
except ValueError:
print("Invalid input! Please enter a valid integer.")
# Run the function
check_even_odd()
Source Code -
def is_prime(n):
"""Function to check if a number is prime"""
if n <= 1:
return False
for i in range(2, int(n**0.5) + 1):
if n % i == 0:
return False
return True
# Taking user input
num = int(input("Enter a number: "))
# Checking and displaying the result
if is_prime(num):
print(f"{num} is a prime number.")
else:
print(f"{num} is not a prime number.")
Aim - Demonstrate the use of a Python debugger (e.g., pdb or an IDE with debugging capabilities) on a sample program with intentional errors. Guide students on setting breakpoints, stepping through code, and examining variable values
Source Code -
def add(a, b):
result = a + b
return result
def main():
x = 10
y = 20
import pdb; pdb.set_trace() # <- Debugger starts here
total = add(x, y)
print("Total:", total)
main()
Aim - Write a Python script that prompts the user to enter their phone number and email ID. It then employs Regular Expressions to verify if these inputs adhere to standard phone number and email address formats.
Source Code -
import re
def validate_phone(phone):
phone_pattern = re.compile(r"^\+?[0-9]{1,3}?[-.\s]?\(?[0-9]{1,4}?\)?[-.\s]?[0-9]{1,4}[-.\s]?[0
9]{1,9}$")
return bool(phone_pattern.match(phone))
def validate_email(email):
email_pattern = re.compile(r"^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$")
return bool(email_pattern.match(email))
def main():
phone = input("Enter your phone number: ")
email = input("Enter your email ID: ")
if validate_phone(phone):
print("Valid phone number")
else:
print("Invalid phone number")
if validate_email(email):
print("Valid email address")
else:
print("Invalid email address")
if __name__ == "__main__":
main()
Aim: Develop a Python script to create two arrays of the same shape and perform element-wise addition, subtraction, multiplication, and division. Calculate the dot product and cross product of two vectors
Source Code -
import numpy as np
# Creating two arrays of the same shape (2x3 for demonstration)
arr1 = np.array([[1, 2, 3], [4, 5, 6]])
arr2 = np.array([[7, 8, 9], [10, 11, 12]])
print("Array 1:")
print(arr1)
print("\nArray 2:")
print(arr2)
# Element-wise addition
addition = arr1 + arr2
print("\nElement-wise Addition:")
print(addition)
# Element-wise subtraction
subtraction = arr1 - arr2
print("\nElement-wise Subtraction:")
print(subtraction)
# Element-wise multiplication
multiplication = arr1 * arr2
print("\nElement-wise Multiplication:")
print(multiplication)
# Element-wise division
division = arr1 / arr2
print("\nElement-wise Division:")
print(division)
# Dot product of two vectors (flatten the arrays for 1D vectors)
dot_product = np.dot(arr1.flatten(), arr2.flatten())
print("\nDot Product of flattened vectors:")
print(dot_product)
# Cross product (only for 3-dimensional vectors, so we'll use 3 elements from each array)
cross_product = np.cross(arr1[0], arr2[0]) # Using the first row as 3D vectors
print("\nCross Product of the first row vectors:")
print(cross_product)
