Need python coding. Need to use "while" loop and "remove".

Write a function deleteall(L, x) to delete all occurrences of the item x from the list L. The function should change the list L in place and not return anything. Use the docstring """Deletes all occurrences of item x from list L""". Do not change the main program.

Expected output: ['A', 'l', 'h', 'm', 'b', 'r']

P.S. Recall our discussion from 4.5 and do not use the for loop.

# Main program (do not change):

L = ['A', 'l', 'h', 'a', 'm', 'b', 'r', 'a']

deleteall(L, 'a')

print(L)
