Computing Fundamentals using Python
1. Basic function to add two numbers
def sum1(n1,n2):#default arguments #1
sum=n1+n2
return sum
s=sum1(5,10)
print ("sum of two numbers",s)
2. Function to check if a number is even or odd
def check(x):#2
if x%2==0:
print("it is an even number",x)
else:
print("it is an odd nnumber",x)
check(34)
def fact(x):#3
if x==0:
return 1
return x*fact(x-1)
print(fact(5))
3.Function to calculate the factorial of a number
def fact(x):#3
if x==0:
return 1
return x*fact(x-1)
print(fact(5))
4. Function to reverse a string
def rev(string):
rev=string[::-1]
return rev
print(rev("siri"))
5. Function to count the number of vowels in a string
def count_vowels(s):
vowels=['A','E','I','O','U','a','e','i','o','u']
return len ([char for char in s if char in vowels])
string="bca course"
total_vowels=count_vowels(string)
print("total vowels",total_vowels)
6. Function to find the maximum among three numbers
def find_max(a,b,c):#6
return max (a,b,c)
print(find_max(12,30,2))
7. Function to generate a list of prime numbers up to a given number
def print_primes(n):
for num in range (2,n+1):
if num>1:
for i in range (2,num):
if (num% i )==0:
break
else:
print(num)
print_primes(30)
8. Function to calculate the power of a number
def CalculatePower(N,X):
P=1
for i in range(1, X+1):
P=P*N
return P
N,X=2,3
print(CalculatePower(N,X))
N,X=3,4
print(CalculatePower(N,X))
9. Function to check if a string is a palindrome
def isPalindrome(s):
return s == s[::-1]
s = "malayalam"
ans = isPalindrome(s)
if ans:
print("Yes")
else:
print("No")
10. Function to calculate the Fibonacci sequence up to n terms
FibArray = [0, 1]
def fibonacci(n):
# Check is n is less
# than 0
if n < 0:
print("Incorrect input")
# Check is n is less
# than len(FibArray)
elif n < len(FibArray):
return FibArray[n]
else:
FibArray.append(fibonacci(n - 1) + fibonacci(n - 2))
return FibArray[n]
# Driver Program
print(fibonacci(9))
11. Function to check if a number is prime
def is_prime(n):
if n <= 1:
return False
# Check divisibility from 2 to n-1
for i in range(2, n):
if n % i == 0:
return False
return True
n = 11
print(is_prime(n))
12. Function to calculate the sum of digits in a number
def getSum(n):
sum = 0
for digit in str(n):
sum += int(digit)
return sum
n = 12345
print(getSum(n))
13. Function to find the second largest number in a list
def find_second_largest(numbers):
return sorted(set(numbers))[-2]
# Example usage
numbers = [10, 20, 4, 45, 99]
print("The second largest number is:", find_second_largest(numbers))
14. Implement a function to perform matrix multiplication
def matrix_multiply(A, B):
# Get the dimensions of the matrices
rows_A = len(A)
cols_A = len(A[0])
rows_B = len(B)
cols_B = len(B[0])
# Initialize the result matrix with zeros
result = [[0 for _ in range(cols_B)] for _ in range(rows_A)]
# Perform matrix multiplication
for i in range(rows_A):
for j in range(cols_B):
for k in range(cols_A):
result[i][j] += A[i][k] * B[k][j]
return result
# Example usage
A = [[1, 2],
[3, 4]]
B = [[5, 6],
[7, 8]]
result = matrix_multiply(A, B)
for row in result:
print(row)
15. Function to generate a password of given length
import random
import string
def generate_password(length):
charecters=string.ascii_letters+string.digits+string.punctuation
return ''.join(random.choice(charecters)for _ in range(length))
print(generate_password(13))
