Example of list below:
chocolate_cake = ["eggs","flour","milk","baking soda", "choco powder"]
------------------------------------------------------------------------
To simpily copy this list you can do the command below:
chocolate_cake2 = chocolate_cake.copy()
bikes = ['trek', 'redline', 'giant']
copy_of_bikes = bikes[:]
a_copy = a_list.copy()
a=[1,2,3,4]
b=a[:]
''' now b has all elements of a'''
# Copy a List
basket = ['apples', 'pears', 'oranges']
new_basket = basket.copy()
new_basket2 = basket[:]
# mixed list
prime_numbers = [2, 3, 5]
# copying a list
numbers = prime_numbers.copy()
print('Copied List:', numbers)
# Output: Copied List: [2, 3, 5]
new_list = old_list.copy()
# Above new_list does not get affected when modifying old_list
new_list = old_list
#Here new_list is also affected if any modifications are made to old_list
