insert(1, 20) print(l) tuple_val = tuple(list_val) print(tuple_val) The tuple is first converted into a list, and the built-in insert() function is used to insert a value in between the existing values. Afterward, the list is converted back to a tuple. Output: [11, 20, 52,...
To create a NumPy array, you can use thenumpy.array()function. You can pass a Python list, tuple, or any array-like object to this function, and it will create a NumPy array. In order to work with an example, first, let’s create a NumPy array usingnumpy.array()method. Before goi...
