要將手機(jī)的時(shí)間格式從24小時(shí)制轉(zhuǎn)換為12小時(shí)制，可以使用以下Python代碼：

def convert_time(time_str):
    if ':' in time_str:
        hours, minutes = map(int, time_str.split(':'))
        return f"{hours}:{minutes}"
    elif 'AM' in time_str or 'PM' in time_str:
        am_pm = time_str.replace('AM', '').replace('PM', '')
        if 'AM' in am_pm:
            return f"{am_pm}:00"
        elif 'PM' in am_pm:
            return f"{00:02d}:{int(am_pm)}"
        else:
            return f"{00:02d}"
    else:
        return "Invalid time format"

time_str = input("請輸入時(shí)間（格式：HH:MM）：")
result = convert_time(time_str)
print("轉(zhuǎn)換后的時(shí)間是：", result)

將上述代碼復(fù)制到Python環(huán)境中運(yùn)行，根據(jù)提示輸入時(shí)間，程序會(huì)輸出轉(zhuǎn)換后的12小時(shí)制時(shí)間。
