Is this code good??

def timeConversion(s):
    hour = int(s[:2])
    minute = s[3:5]
    second = s[6:8]
    am_pm = s[8:]

    if am_pm == "AM":
        if hour == 12:
            print(f"0{hour - 12}:{minute}:{second}")
        else:
            print(f"0{hour}:{minute}:{second}")

    elif am_pm == "PM":
        if hour == 12:
            print(f"{hour}:{minute}:{second}")
        else:
            print(f"{hour + 12}:{minute}:{second}")
