Top 10 Basic Code For Python With Solution
Check out some of the basic Python codes with the solutions below.
1. Write a Python program to swap two numbers.
Ans: Check the Python code below to swap two numbers using Python.
| Basic Code for Python |
| num1 = float(input(“Enter the first number: “)) //prompt user for entering number
num2= float(input(“Enter the second number: “)) #Display the original number first print(f “Original Values: num1 = {num1}, num2 = {num2}”) #Swap two numbers using the temp variable temp = num1 num1 = num2 num2 = temp #Display the swapped numbers print(f “Value after Swapping values: num1 = {num1}, num2 = {num2}”) |
Output
| Enter the first number: 14
Enter the second number: 51 Original values: num1 = 14, num2 = 51 Value after Swapping: num1 = 51, num2 = 14 |
2. Write a program to add two numbers using Python.
Ans: Adding two numbers in Python is one of the most basic Python problems for beginners. Check the input and output samples for the Python problem given above.
| Basic Code for Python |
| #Basic code for Python to add two numbers
num1 = float(input(“Enter the first number: “)) //prompt user for entering number num2= float(input(“Enter the second number: “)) #Create a variable to store the sum of the two numbers. sum = num1 + num2 print(f”The sum of {num1} and {num2} is {sum}”) |
Output
| Enter the first number: 15
Enter the second number: 7 The sum of 15 and 7 is 22 |
3. Write a basic Python program for finding the factorial of a number.
Ans: Factorial of number is the repeated multiplication of first n integers. It can only be calculated for positive integers. Let us create a Python function to find the factorial of a number n.
| Basic Code for Python |
| #Function for finding the factorial of a number using Python
def factorial (n): if (n == 1 or n == 0): //If numbers are 0 and 1, then return 1. return 1 else: return n * factorial (n-1) //Factorial using recursion int num = int(input(“Enter a number to calculate factorial of number: ”) print(“Factorial of”, num, “is”, factorial(num)) |
Output
| Enter the number to calculate the factorial:
6 Factorial of 6 is 720 |
4. Write a program to determine the sum of the first n natural numbers, Write a Python program.
Ans: The sum of the first natural number can be calculated directly using the formula n * (n+1) // 2. However, we will use the basic approach in the code below for beginners.
| Basic Code for Python |
| #Function to calculate the sum of n numbers using Python. It can be calculated using simple repeated addition.
num = int (input(“Enter the number: ”)) if num<0: print(“Negative numbers are not allowed.”) else: sum = 0 i = num while(i>0): sum+=i i = i-1 print(f “ Sum of first {num} natural number is”, num) |
Output
| Enter the number: 6
Sum of first 6 natural number is 21 |
5. Write a Python program to check whether a string is a palindrome.
Ans: A palindrome is a type of string in which, on reversing, the digits are the same. For example, when we reverse “radar”, it is the same. These strings are palindrome.
| Basic Code for Python |
| #Python function to check whether a string is a palindrome.
def isPalindrome(str) #Remove spaces and convert them into lowercase letters. final_string = ‘ ’.join(str.split()).lower() return rev = final_string[: : -1] int str_input = input(“Enter a string: ” ) if (is_palindrome(str_input): print(f “{str_input} is a palindrome.”) else: print(f”{str_input} is not a palindrome.”) |
Output
| Enter a string:
Radar Radar is a palindrome. |
6. Write a Python program to reverse a string.
Ans: In Python, strings can easily be reversed using slicing or a while loop in reverse order. Check the code below for implementation using Python.
| Basic Code for Python |
| #Python function to check whether a string is a palindrome.
str = input(“Enter a string: ”) reverse_str = str[ : : -1] print(f “The reversed string is {reverse_str}.”) |
Output
| Enter a string:
Physics Wallah The reversed string is hallawscisyhP. |
7. Write a Python program to check whether a year is a Leap Year.
Ans: A Leap Year occurs every year, having 366 days. The one extra day is in February. A year that is divisible by 4 and not 100. Also, if they are divisible by 400, then it is a leap year.
| Basic Code for Python |
| #Function to predict whether a given year is a Leap year.
def is_Leap_Year (year): #If the given year is divisible by 4 and not divisible by 100, then it is a leap year. Also, if the given year is divisible by 400, then it is a leap year. if (year%4 == 0 and year%100!=0) or (year%400 ==0): return True else: return False year_inp = int(input(“Enter a year:”)) //Take input from the user. if is_Leap_Year(year_inp): print(f “{year_inp} is a leap year.”) else: print(f”{year_inp} is not a leap year.”) |
Output
8. Write a Python program to calculate the square of a given number.
Ans: The given number is multiplied twice to get the square of the given number. Check out the program below to calculate the square of a given number.
| Basic Code for Python |
| #First, take the input from the user
num = int(input(“Enter the number to find square: ”)) print (“Square of the given number is “,num*num) |
Output
| Enter the number to find square:
9 Square of the given number is 81 |
9. Write a Python Program to check whether the given character is a vowel or consonant.
Ans: We can use if and else command statements to check whether a given character is a vowel or consonant. There are five vowels in the English alphabet: a, e, i, o, u. Check out the Python code below.
| Basic Code for Python |
| #Ask the user for input of a character (vowel or consonant)
ch = input(“Enter a character: “) if(ch == ‘a’ or ch == ‘e’ or ch == ‘i’ or ch == ‘o’ or ch == ‘u’): print(“The given character”, ch, “is a vowel.”) //if the character is found to be vowel else: Print (“Given character”, ch, “is a consonant.”) //if the given character is consonant. |
Output
| Enter a character:
e The given character e is a vowel. |
10. Write a Python program to remove spaces from a string without using inbuilt functions.
Ans: We have to write a Python program without using any built-in function to remove spaces between a string. Check the implementation below.
| Basic Code for Python |
| #First take input from the user
str = input(“Enter a string: ”) result = “ ” #iterate string one by one for i in str: if i!= ‘ ’: result +=i print(“The given string after removing all spaces is: ”, result) |
Output
| Enter a string
Physics Wallah The given string after removing all spaces is: PhysicsWallah |
