In Python, the user can check whether a character is a number or not by using the isdigit(), isnumeric() method or by using the type casting method.
To check if a number is prime in Python, you can use an optimized iterative method. First, check if the number is less than or equal to 1; if so, it’s not prime. Then, iterate from 2 to the square root of the number, checking for divisibility. If the number is divisible by any...
Python Code:def test(n): if (n>0): t = sum(map(int, str(n))) return not n % t n = 666 print("Original number:", n) print("Check the said number is a Harshad number or not!") print(test(n)) n = 11 print("\nOriginal number:", n) print("Check the said number is...
Python Code:# Define a function named 'perfect_number' that checks if a number 'n' is a perfect number def perfect_number(n): # Initialize a variable 'sum' to store the sum of factors of 'n' sum = 0 # Iterate through numbers from 1 to 'n-1' using 'x' as the iterator for x...
If the remainder is not zero, the number is odd. Source Code # Python program to check if the input number is odd or even. # A number is even if division by 2 gives a remainder of 0. # If the remainder is 1, it is an odd number. num = int(input("Enter a number: ")) if...
