Làm cách nào để kiểm tra số nguyên dương đầu vào của người dùng trong Python?
Sử dụng phương thức chuỗi isdigit[] để kiểm tra đầu vào của người dùng là số hay chuỗi . Ghi chú. Hàm isdigit[] sẽ chỉ hoạt động với các số nguyên dương. tôi. e. , nếu bạn vượt qua bất kỳ số float nào, nó sẽ không hoạt động. Vì vậy, tốt hơn là sử dụng phương pháp đầu tiên.
Loại float nào là tích cực trong Python?
