将元组传递给Python函数

Question

I know that there has been a bit of discussion about passing a tuple to a function; I checked all of them but couldn't solve my problem. So here is the problem. I am trying to pass two tuples into a function and do calculations on them. Here is a sample:

c=(2,3)
d=(4,5)

def func1((a(0),a(1)),(b(0),b(1))):
    return(a(0)*b(1))

I also tried

c=(2,3)
d=(4,5)

def func1(a,b):
    return(a(0)*b(1))

Both of them give error invalid syntax or 'tuple' object is not callable . Any help is appreciated. Please read it carefully before marking it "duplicate". Thank you.

Answer 1

First example is invalid python syntax. Second, index access uses square brackets.

def func1(a,b):
    return(a[0] * b[1])
