python小練習：攝氏度轉華氏度

# Author:Hiuhung Wan
#輸入一個攝氏溫度值，轉換成華氏溫度值
notfalse = not False
while notfalse:
    degree_centigrade = input("Please Input the Degree Centigrade:")
    if degree_centigrade.isdigit():
        degree_centigrade = int(degree_centigrade)
        fahrenheit = '%.2f'%(1.8*degree_centigrade + 32)   #保留兩位小數
        print("Your input is",degree_centigrade ,"degrees Celsius,\nConverted to Fahrenheit is",fahrenheit,".","\nPress Q or q to exit.")
    elif degree_centigrade == "q" or degree_centigrade == "Q":
        notfalse = False
    else:
        print("Please enter a number!")

　　目前輸入小數與負數，會有BUG
