Why am I getting a type error?

[WagmoreBarkless]

This should be simple.

I am using NumPy's ndarray, and taking the shape() of the 1st element like this:X.shape[0]. As expected, this is an integer that evaluates to 100.

When I try to add that to integer literal, I get a type error.

type(X.shape[0])
Out[87]: 
int
type(1+X.shape[0])
Out[88]: 
int
type(X)
Out[89]: 
numpy.ndarray

Error:
Traceback (most recent call last):
  File "C:\Users\WB\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py", line 2881, in run_code

    zz=1 + X.shape[0]
TypeError: unsupported operand type(s) for +: 'int' and 'tuple'

As you can see from the trace, I should be adding two integers. Why does it think one of them is a tuple?
