>> Here's a list of some basic Python programs
covering different concepts:
1. Hello, World! Program:
print("Hello World!")
Output :
Hello world!
2. Sum of Two Numbers:
num1 = int(input("Enter value of num1: "))
num2 = int(input("Enter value of num2: "))
sum_result = num1 + num2
print("Sum:", sum_result)
Output :
Enter value of num1: 34
Enter value of num2: 56
Sum: 90
3. Finding the Largest Number in a List:
numbers = [12, 45, 89, 23, 67]
max_number = max(numbers)
print("Largest Number:", max_number)
Output :
Largest Number: 89
4. Factorial of a Number:
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)
#user input any number
num = int(input("Enter number of factorial found: "))
print("Factorial of", num, "is", factorial(num))
Output :
Enter number of factorial found: 5
Factorial of 5 is 120
5. Checking if a Number is Prime:
def is_prime(n):
if n < 2:
return False
for i in range(2, int(n**0.5) + 1):
if n % i == 0:
return False
return True
num =int(input("Enter the number: "))
if is_prime(num):
print(num, "is a prime number.")
else:
print(num, "is not a prime number.")
Output:
Enter the number: 6
6 is not a prime number.
Enter the number: 27
27 is not a prime number.
6. Reversing a String:
#user input the string
string = input("Enter the string: ")
reversed_string = string[::-1]
print("Reversed String:", reversed_string)
Output :
Enter the string: Hello Python
Reversed String: nohtyP olleH
7. Counting the Occurrences of Each Character in a String:
#user enter any string from a to z
string = input("Enter any string from a to z: ")
char_counts = {}
for char in string:
char_counts[char] = char_counts.get(char, 0) + 1
print("Character Counts:", char_counts)
Output :
Enter any string from a to z: jaishreeram
Character Counts: {'j': 1, 'a': 2, 'i': 1, 's': 1, 'h': 1, 'r': 2, 'e': 2, 'm': 1}
8. Checking if a String is a Palindrome:
def is_palindrome(s):
return s == s[::-1]
string = input("Enter any string : ")
if is_palindrome(string):
print(string, "is a palindrome.")
else:
print(string, "is not a palindrome.")
Output :
Enter any string : aabbaa
aabbaa is a palindrome.
9. Fibonacci Series:
def fibonacci(n):
if n <= 0:
return []
elif n == 1:
return [0]
elif n == 2:
return [0, 1]
else:
series = [0, 1]
for i in range(2, n):
next_num = series[-1] + series[-2]
series.append(next_num)
return series
n_terms = int(input("Enter the number: "))
fib_series = fibonacci(n_terms)
print("Fibonacci Series:", fib_series)
Output :
Enter the number: 10
Fibonacci Series: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
These programs cover various concepts like printing,
basic arithmetic,lists, functions, loops, conditionals,
and string manipulation in Python. They should give you
a good starting point to explore different aspects of Python programming.
