我目前仍在學(xué)習(xí) Python 的基礎(chǔ)知識(shí)。我看到其他人將攝氏度轉(zhuǎn)換為華氏度，這就像 10 行。雖然我的代碼超過(guò) 40 行。我沒(méi)有完全理解'返回'的意義是什么，所以我選擇了一個(gè)簡(jiǎn)單的項(xiàng)目來(lái)理解它。但是當(dāng)我意識(shí)到我的代碼對(duì)于如此簡(jiǎn)單的事情來(lái)說(shuō)太長(zhǎng)了。感覺(jué)我應(yīng)該做很多困難的項(xiàng)目，因?yàn)槲以诤?jiǎn)單的事情上使用了很多行。對(duì)不起，我是新手，我很想通過(guò)做項(xiàng)目來(lái)學(xué)習(xí)。困難的初學(xué)者項(xiàng)目的任何建議都會(huì)有所幫助。謝謝！import timedegree_sign = u'\N{DEGREE SIGN}'def fahrenheit():    degree = int(input('\nHow many degrees is it currently in Fahrenheit?: '))    a = round((degree - 32) * 5/9)        return adef celsius():    degree = int(input('\nHow many dgrees is it currently in Celsius?: '))    a = round((degree * 9/5) + 32)        return aprint("Welcome to my first weather conversion!\n")weather = input('Do you want to convert to Fahrenheit or Celsius (c/f)? \n').lower()if weather == "c":    time.sleep(0.5)    print(f'It is currently {fahrenheit()}{degree_sign}C.')elif weather == "f":    time.sleep(0.5)    print(f'\nIt is currently {celsius()}{degree_sign}F.')else:    while True:        print("\nI'm sorry I don't understand.\n")        weather = input('Do you want to convert to Fahrenheit or Celsius (c/f)? \n').lower()        if weather != "c" and weather != "f":            continue        elif weather == "c":            time.sleep(0.5)            print(f'\nIt is currently {fahrenheit()}{degree_sign}C')            break        elif weather == "f":            time.sleep(0.5)            print(f'\nIt is currently {celsius()}{degree_sign}F.')            break
