Hướng dẫn how do you write a factorial code in python? - làm thế nào để bạn viết mã giai thừa trong python?

Trong bài viết này, bạn sẽ học cách tìm thấy giai thừa của một số và hiển thị nó.

Để hiểu ví dụ này, bạn nên có kiến ​​thức về các chủ đề lập trình Python sau:

  • Python nếu ... tuyên bố khác
  • Python cho vòng lặp
  • Đệ quy Python

Nấp của một số là sản phẩm của tất cả các số nguyên từ 1 đến số đó.

Ví dụ, giai thừa của 6 là 1*2*3*4*5*6 = 720. Nấp không được xác định cho các số âm và giai thừa của số 0 là một, ____10.

Đơn vị của một số sử dụng vòng lặp

# Python program to find the factorial of a number provided by the user.

# change the value for a different result
num = 7

# To take input from the user
#num = int(input("Enter a number: "))

factorial = 1

# check if the number is negative, positive or zero
if num < 0:
   print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
   print("The factorial of 0 is 1")
else:
   for i in range(1,num + 1):
       factorial = factorial*i
   print("The factorial of",num,"is",factorial)

Đầu ra

The factorial of 7 is 5040

Lưu ý: Để kiểm tra chương trình cho một số khác, thay đổi giá trị của

The factorial of 7 is 5040
1. To test the program for a different number, change the value of
The factorial of 7 is 5040
1.

Ở đây, số lượng mà giai thừa sẽ được tìm thấy được lưu trữ trong

The factorial of 7 is 5040
1 và chúng tôi kiểm tra xem số đó là âm, bằng không hoặc dương bằng câu lệnh
The factorial of 7 is 5040
3. Nếu số là dương, chúng tôi sử dụng chức năng
The factorial of 7 is 5040
4 và
The factorial of 7 is 5040
5 để tính toán giai thừa.

Lặp đi lặp lại Factorial*i (giá trị trả về)
i = 11 * 1 = 1
i = 21 * 2 = 2
i = 32 * 3 = 6
i = 46 * 4 = 24
i = 524 * 5 = 120
i = 6120 * 6 = 720
i = 7720 * 7 = 5040

Đơn vị của một số sử dụng đệ quy

    Công thức cho giai thừa trong Python là gì?

    Để tìm giai thừa Python của một số, số được nhân với tất cả các số nguyên nằm giữa 1 và số.Về mặt toán học, nó được đại diện bởi!Vì vậy, ví dụ, 5!sẽ là 5 x 4 x 3 x 2 x 1, đó là 120. Không xác định số gốc cho các số âm.the number is multiplied with all the integers that lie between 1 and the number itself. Mathematically, it is represented by “!”. Thus, for example, 5! will be 5 x 4 x 3 x 2 x 1, that is 120. Factorial for negative numbers is not defined.

    Có một phương pháp giai thừa trong Python?

    Không nhiều người biết, nhưng Python cung cấp một chức năng trực tiếp có thể tính toán giai thừa của một số mà không viết toàn bộ mã để tính toán.Phương pháp này được định nghĩa trong mô -đun Math Math của Python.python offers a direct function that can compute the factorial of a number without writing the whole code for computing factorial. This method is defined in “math” module of python.
