尝试执行基本代码但产生错误

Question

Just trying some code out:

a_leg = 5
b_leg = 5

hyp = (a_leg**2)(b_leg**2)
print(hyp)

I get the below error:

hyp = (a_leg**2)(b_leg**2)

TypeError: 'int' object is not callable

What does this mean? I know it is very basic but will appreciate your help.

Thanks

Answer 1

You are getting this because of

hyp = (a_leg**2)(b_leg**2)

In programming languages you have to explicitly use operators. In this case, the correct code would be:

hyp = (a_leg**2)*(b_leg**2)

notice the * between those two brackets.

Answer 2

You are getting this error because:

(a_leg**2)

returns an integer that is not callable. You can make a function to calculate the hypotenuse like these:

from math import sqrt

a_leg = 5
b_leg = 5

def hyp(a, b):
    h = sqrt((a**2) + (b**2))
    return h

print(hyp(a_leg, b_leg))
