我应该如何定义结果？

Question

我正在运行下面的代码，并得到结果未定义的错误

inp = input("Enter the value to convert = ")
degree = int(inp[:-1])
i_conversion = inp[-1]
if i_conversion.upper == "C":
    result = int(round((9 * degree) / 5 + 32))
    o_conversion = "Fahrenheit"
elif i_conversion.upper == "F":
    result = int(round((degree - 32) * 5 / 9))
    o_conversion = "Celsius"

print("The temp is", result)

Answer 1

str.upper是函数而不是属性；它后面需要括号Docs

inp = input("Enter the value to convert = ")
degree = int(inp[:-1])
i_conversion = inp[-1]
if i_conversion.upper() == "C":
    result = int(round((9 * degree) / 5 + 32))
    o_conversion = "Fahrenheit"
elif i_conversion.upper() == "F":
    result = int(round((degree - 32) * 5 / 9))
    o_conversion = "Celsius"

print("The temp is", result)
