Question

2. Please using python code to complete the following operations using "NumPy" (a) Create a 1D array (name it as "arr_1") of numbers from 0 to 9 (desired output: [0 1 2 3 4 5 6 7 8 9]), and print it out. (b) Extract all odd numbers from "arr_1", and print it out. (c) Replace all odd numbers in "arr_1" with -1, and print it out. (d) Print out the elements in "arr_1" that indexed from 2 to 5 (desired output: [2 3 4 5]). (e) Print out the data type of "arr_1"
