Explanation
- Line 1: We import the
numpymodule. - Line 3: We create an input array,
a, using thearray()function. - Line 6: We call the
repeat()function and passaand2as arguments. The function will create an array in which the elementawill be repeated twice. - Line 9: We print the new array,
my_array.
