remove an element from the beginning of an array in python

To remove an element from the beginning of an array (or list) in Python, you can use slicing. Slicing is a way to extract a subset of elements from an array by specifying a start and end index.

To remove the first element of an array, you can specify a slice that starts from the second element (index 1) and ends at the last element using the colon operator :.

Here's an example:

main.py
my_array = [1, 2, 3, 4, 5]
my_array = my_array[1:]
print(my_array)  # Output: [2, 3, 4, 5]
91 chars
4 lines

In this example, we create an array my_array with 5 elements. We then use slicing to create a new array that starts from the second element (my_array[1]) and ends at the last element (my_array[-1]). Finally, we assign the new array back to my_array to replace the original array. The output shows that the first element has been removed from the array.
