FOMAT: list.insert(index,element)
hey you, I want you to remember that insert function
takes the index as the parameter okay?
Just remember it as "insert" starts with "i" so the first parameter of insert
also starts with i
Sounds crazy but workshave a good day. Dont forget this concept.

# list.insert(before, value)
list = ["a", "b"]
list.insert(1, "c")
print(list) # ['a', 'c', 'b']

# create a list of vowels
vowel = ['a', 'e', 'i', 'u']
# 'o' is inserted at index 3 (4th position)
vowel.insert(3, 'o')
print('List:', vowel)
# Output: List: ['a', 'e', 'i', 'o', 'u']

l = list(range(3))
print(l)

#add item to the beginning of list – at index 0

a.insert(len(a),x) is equivalent to a.append(x)

#add item to specific index
