As long as its expression continues to be True, a while loop can keep running indefinitely. For the loop to terminate, the conditional expression must change to False at some point. This means at least one of the variables used in the expression must be updated somewhere within the code blo...
The program checks if the number is 0 and returns 1(factorial of 0 is 1). Then thewhile loopchecks the condition (n >=1) to see if our n is equal to 1 or greater than 1. Each time when this condition is TRUE, our program computes the formula in the loop block Let’s use the...
Also read: Python while loopBefore we wrap up, let’s put your knowledge of Python for loop to the test! Can you solve the following challenge? Challenge: Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive...
may not be able to rewrite using a for loop 咱们来个计算阶乘的例子,两个循环代码如下: #for loop solution n = 5 fact = 1 for i in range(2, n + 1): fact = fact * i print(str(n) + ' factorial is ' + str(fact)) #while loop solution n = 5 fact = 1 i = 2 #while要初...
def factorial(n): fact = 1 for i in range(1, n + 1): fact *= i return fact print(factorial(5)) Output: Explanation: Here, the factorial() function calculates the product of all numbers from 1 to n using a loop Function to Reverse a String This function takes a string as inp...

This approach simplifies code and leads to elegant solutions, especially for tasks with repetitive patterns. Example of a Python program that calculates the factorial of a number using recursion: def factorial(n): if n <= 1: return 1 else: return n * factorial(n - 1)# Input from the ...
