Question
what is the result of the following lines of code:a=np.array([0,1])b=np.array([1,0])print( a @b )
Solution
The result of the following lines of code is 0.
Here's the step by step explanation:
-
First, we import the numpy library and create two numpy arrays 'a' and 'b'. 'a' contains elements [0,1] and 'b' contains elements [1,0].
-
Then, we use the '@' operator. This operator performs matrix multiplication between two arrays.
-
The matrix multiplication of 'a' and 'b' is calculated as follows: (01 + 10) = 0
-
Finally, we print the result which is 0.
