温度转换

#e1.1 TempConvert.py

def tempConvert(ValueStr):
    if ValueStr[-1] in ['F','f']:
        C=(eval(ValueStr[0:-1])-32)/1.8
        print("The result temperature is {:.2f}C".format(C))
    elif ValueStr[-1] in ['C','c']:
        F = (eval(ValueStr[0:-1])*1.8)+32
        print("The result temperature is {:.2f}F".format(F))
    else:
        print("Input format error!")

TempStr = input("请输入带有符号的温度值：")
tempConvert(TempStr)

请输入带有符号的温度值：>? 82F
The result temperature is 27.78C

请输入带有符号的温度值：>? -30C
The result temperature is -22.00F
