Bước 1: Chúng tôi muốn bắt đầu bằng cách nhập mô-đun thời gian trước .

Bước 2: Sau đó, chúng tôi sẽ lấy thông tin đầu vào của người dùng bằng cách hỏi họ thời lượng đếm ngược tính bằng giây. Khi nhận thông tin đầu vào của người dùng, nó thường ở định dạng chuỗi, vì vậy bạn phải chuyển đổi thông tin đầu vào của người dùng được lưu trữ đó thành một số nguyên.

Bước 3: Tạo một hàm gọi là countdown () , trong đó chúng ta sẽ chạy một vòng lặp while chạy đếm ngược cho đến khi đầu vào do người dùng truyền chuyển sang 0. (Hãy nghĩ đến việc sử dụng bộ đếm và nối chuỗi cho phần này)

Bước 4: Sử dụng hàm divmod () từ mô-đun thời gian đã nhập của chúng tôi để tính số phút và giây.

Bước 5: In phút và giây trên màn hình bằng cách sử dụng biến TIMEFORMAT .

Bước 6: Sử dụng end = '\ r', chúng ta có thể buộc con trỏ quay lại đầu màn hình (trong python nó được gọi là ký tự xuống dòng) để dòng tiếp theo được in sẽ ghi đè dòng được in.

Bước 7 : Sử dụng phương thức timesleep () từ mô-đun thời gian để làm cho mã của bạn đợi trong 1 giây. Sau đó, chúng tôi giảm thời gian để vòng lặp while có thể hội tụ.

Bước 8: In một câu lệnh ở cuối vòng lặp để biểu thị sự kết thúc của vòng lặp:

My classroom is on the second floor. I‟m in grade 7, class 7A. Our class starts at 7.00 and finishes at 11.30. At school we learn many things, but I like Literature and English best. I also like Music, Sports and Art. We often have recess at 9.20. We usually drink, eat and talk at recess. We sometimes play games like blind man‟s bluff or catch. We often make much noise at recess.

Read the passage and choose the best answer (A, B, or C) to the following questions (5 pts) What do you often do after school? In my school, there are a lot of clubs which students can take part in after school hours. The club that has the biggest number of members is the swimming club called “Blue Dolphins”. I myself love swimming so I am a member of this club. I go to the swimming pool twice a day and swim for about an hour. I‟m really interested in swimming breaststroke because it helps me move as fast as I can. I‟m also fond of backstroke. I swim backstroke when I want to relax, breathe and let my body float freely. It‟s very relaxing. The second club I would like to mention is the charity club. Its name is “Golden Heart”. Members of the club often do community service. This month, they are conducting a clean-up campaign to protect the environment around the school. They collect trash, clean the toilet area, and grow plants. I am not a Golden Heart‟s member, but I participate in their activities whenever I can. If you can sing, dance or play musical instruments, the musical club “Heartstrings” is definitely for you. The president of the club is Mike, my best friend. He is not only good-looking but also sings beautifully and plays the guitar very well. In conclusion, we should do as many activities as possible in our free time to have good health and a fresh mind to prepare for lessons in class. Spending all our time studying is not a good idea. 6.
