'''
Create a function named divisible_by_ten() that takes a list of numbers named nums as a parameter.

Return the count of how many numbers in the list are divisible by 10.
'''
def divisible_by_ten(nums):
  counter = 0
  for num in nums:
    if num % 10 == 0:
      counter += 1
  return(counter)


# print(divisible_by_ten([20, 25, 30, 35, 40]))
# 3

'''
Create a function named add_greetings() which takes a list of strings named names as a parameter.

In the function, create an empty list that will contain each greeting. Add the string 'Hello, ' in front of each name in names and append the greeting to the list.

Return the new list containing the greetings.
'''
def add_greetings(names):
  hello_names = []
  for name in names:
    hello_names.append("Hello, " + name)
  return(hello_names)



# print(add_greetings(["Owen", "Max", "Sophie"]))
# Output: ['Hello, Owen', 'Hello, Max', 'Hello, Sophie']

'''
Write a function called delete_starting_evens() that has a parameter named my_list.

The function should remove elements from the front of my_list until the front of the list is not even. The function should then return my_list.

For example if my_list started as [4, 8, 10, 11, 12, 15], then delete_starting_evens(my_list) should return [11, 12, 15].

Make sure your function works even if every element in the list is even!
'''
def delete_starting_evens(my_list):
  while (len(my_list)) > 0 and my_list[0] % 2 == 0:
    my_list = my_list[1:]
  return my_list

# print(delete_starting_evens([2, 4, 76, 120, 5]))
# [5]

'''
Create a function named odd_indices() that has one parameter named my_list.

The function should create a new empty list and add every element from my_list that has an odd index. The function should then return this new list.

For example, odd_indices([4, 3, 7, 10, 11, -2]) should return the list [3, 10, -2].
'''
def odd_indices(my_list):
	odds_list = []
	for i in range(1, len(my_list), 2):
		odds_list.append(my_list[i])
	return(odds_list)

# print(odd_indices([4, 3, 7, 10, 11, -2]))
# [3, 10, -2]
