Trong bài viết này, bạn sẽ học cách tìm thấy giai thừa của một số và hiển thị nó.
Nấp của một số là sản phẩm của tất cả các số nguyên từ 1 đến số đó.
To test the program for a different number, change the value of
1 và chúng tôi kiểm tra xem số đó là âm, bằng không hoặc dương bằng câu lệnh
3. Nếu số là dương, chúng tôi sử dụng chức năng
6 là một hàm đệ quy tự gọi. Ở đây, chức năng sẽ tự gọi mình bằng cách giảm giá trị của x.
Để tìm hiểu về hoạt động của đệ quy, hãy truy cập đệ quy Python.

Đơn vị của một số nguyên không âm, là phép nhân của tất cả các số nguyên nhỏ hơn hoặc bằng n. Ví dụ: giai thừa 6 là 6*5*4*3*2*1 là 720.
