我收到以下错误,似乎无法弄清楚如何修复。遵循逻辑,我调用3个函数,所有3个返回值为float,然后我对存储的返回值执行一些数学运算并将其打印为float。那么哪里出错了?我在A面输入4,在B面输入5。
错误消息:
输入A面的长度:4.0 输入B面的长度:5.0

print("The length of side C 'the hypotenuse' is {}".format(lengthHypotenuse))
#The getLengthA function prompts for and returns length of side A

def calculateHypotenuse(a,b):
return math.sqrt(a^2 + b^2)
main()
print()
print('End of program!')
答案 0 :(得分:1)
^
是bitwise XOR operator,而不是幂运算符:
^运算符产生其参数的按位XOR(异或),它必须是整数
您需要使用**
,而 是权力运营商:
def calculateHypotenuse(a,b):
return math.sqrt(a**2 + b**2)
