Python中打字练习的代码

以下是一个简单的Python打字练习的代码：

import time

def typing_test():
    text = "The quick brown fox jumps over the lazy dog"
    print("Type the following sentence as fast as you can:\n")
    print(text)
    input("Press Enter to start...")
    start_time = time.time()
    user_input = input()
    end_time = time.time()
    time_taken = end_time - start_time
    accuracy = calculate_accuracy(text, user_input)
    print(f"Time taken: {time_taken:.2f} seconds")
    print(f"Accuracy: {accuracy:.2f}%")

def calculate_accuracy(text, user_input):
    correct_chars = 0
    for i in range(len(user_input)):
        if i >= len(text):
            break
        if user_input[i] == text[i]:
            correct_chars += 1
    accuracy = (correct_chars / len(text)) * 100
    return accuracy

typing_test()

该代码会输出一段文本，要求用户尽快输入该文本并计算时间和准确率。用户输入后，程序会计算时间和准确率，并输出结果。
