Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, for input5, the output should be 120 1 2 def factorial(n): Check Code Share on: Did you find this...
To find the factorial, fact() function is written in the program. This function will take number (num) as an argument and return the factorial of the number.# function to calculate the factorial def fact(n): if n == 0: return 1 return n * fact(n - 1) # Main code num = 4 #...
# Function to calculate the factorial of a number 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 Reve...
print(factorial(m) // (factorial(n) * factorial(m - n))) # factorial函数也是内置函数,事实上要计算阶乘可以直接使用这个 # 现成的函数而不用自己定义 # 通过导入的math模块,来调用factorial函数来求阶乘运算 import math m = int(input('m = ')) n = int(input('n = ')) print(math.factorial(...

It gets worse quickly: 21,891 calculations are needed for fibonacci(20) and almost 2.7 million calculations for the thirtieth number. This is because the code keeps recalculating Fibonacci numbers that are already known. The usual solution is to implement Fibonacci numbers using a for loop and a...
