我收到以下错误,似乎不知道如何修复。按照逻辑,我调用 3 个函数并将所有 3 个返回值作为浮点数,然后对存储的返回值执行一些数学运算并将其打印为浮点数。那么到底是哪里出了问题呢?我为 A 面输入 4,为 B 面输入 5。
错误信息:
输入 A 边的长度:4.0
输入 B 边长度:5.0

print()
print('End of program!')
^
在Python中是按位异或运算符 https://docs.python.org/3/reference/expressions.html#grammar-token-xor_expr,不是幂运算符:
^ 运算符产生其参数的按位 XOR(异或),该参数必须是整数
你需要使用**
相反,哪个is电力运营商:
def calculateHypotenuse(a,b):
return math.sqrt(a**2 + b**2)
