Explanation
- Line 1: We import the
numpymodule. - Line 4: We use the
numpy.array()function to create a1Darray variable. - Line 7: We implement the
ndarray.tolist()method on the arraymyarray. The output is assigned to a new variablemylist. - Line 9: We print the variable
mylist. - Line 12: We use the
type()function to check for the data type of the object variablemylist.
