Randint () là một hàm sẵn của mô -đun ngẫu nhiên trong Python3. Mô -đun ngẫu nhiên cho phép truy cập vào các chức năng hữu ích khác nhau và một trong số chúng có thể tạo các số ngẫu nhiên, đó là randint (). & Nbsp; cú pháp: & nbsp; is an inbuilt function of the random module in Python3. The random module gives access to various useful functions and one of them being able to generate random numbers, which is randint(). Show randint(start, end) Tham số: & nbsp; (start, end) : Both of them must be integer type values. Trả về: & nbsp; A random integer in range [start, end] including the end points.

Randint ngẫu nhiên hoạt động như thế nào trong Python?Về cơ bản, phương thức randint () trong Python trả về giá trị số nguyên ngẫu nhiên giữa hai giới hạn thấp hơn và cao hơn (bao gồm cả hai giới hạn) được cung cấp dưới dạng hai tham số.Cần lưu ý rằng phương pháp này chỉ có khả năng tạo ra giá trị ngẫu nhiên loại số nguyên.returns a random integer value between the two lower and higher limits (including both limits) provided as two parameters. It should be noted that this method is only capable of generating integer-type random value.
Randint tạo ra ngẫu nhiên có thể tạo ra những gì?hàm randint () để có được một số nguyên ngẫu nhiên từ phạm vi bao gồm.Ví dụ, ngẫu nhiên.Randint (0, 10) sẽ trả về một số ngẫu nhiên từ [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10].a random integer number from the inclusive range. For example, random. randint(0, 10) will return a random number from [0, 1, 2, 3, 4, 5, 6, 7, 8 ,9, 10].
Ngẫu nhiên làm ngẫu nhiên trong Python?Phương thức ngẫu nhiên ngẫu nhiên () Phương thức ngẫu nhiên () Phương thức trả về một số nổi ngẫu nhiên trong khoảng từ 0 đến 1.returns a random floating number between 0 and 1.
Sự khác biệt giữa hàm ngẫu nhiên () và randint () là gì?Sự khác biệt giữa lệnh ngẫu nhiên () và randint (), lệnh ngẫu nhiên sẽ tạo ra giá trị rondom có trong một danh sách/từ điển nhất định. Và lệnh randint sẽ tạo ra một giá trị số nguyên ngẫu nhiên từ danh sách/từ điển đã cho.The random command will generate a rondom value present in a given list/dictionary. And randint command will generate a random integer value from the given list/dictionary. |
