Python 中的转义序列在 CMD 中不起作用

Question

import time
listy = ['timer','stopwatch']

def intro():
    print("This is a program which contains useful tools")
    print(listy)

def timer():
    x = int(input("How long Seconds ?"))
    while x > 0:
        print(x)
        time.sleep(1)
        x -= 1

def stopwatch():
    verif = input("Do you want to start y/n \n")
    if verif == 'y':
        x = 0
        while True:
            print(x, end = "\b"*5)
            time.sleep(1)
            x += 1

def main():
    intro()
    decider = input("Which Program?")
    if decider.lower() == 'timer':
        timer()
    elif decider.lower() == 'stopwatch':
        stopwatch()

main()

在这段代码中，我不知道为什么 \b 转义序列不能在 cmd 或空闲状态下工作，谁能解释为什么？是不是因为逻辑错误？

可能需要冲洗。怎么样...

print("{0}{1}".format("\b"*5, x), end="", flush=True)
