Code-Snippets

## List copies

a = 40
another_list = [6, 4, 1, 2, 5, a]
list2 = list(another_list) #.copy()
another_list.sort()

print(another_list)
print(list2)

## Nested list copies

# create a list
inner_list = [40, 50, 60]

outer_list = [6, 4, 1, 2, 5, inner_list]
copy_outer_list = list(outer_list) #.copy()
# copy_outer_list = outer_list.copy()

print(outer_list)
print(copy_outer_list)

inner_list[2] = 500
outer_list[1] = 100
print(outer_list)
print(copy_outer_list)

Maybe extend the modifying tricks section

numbers = [1, 2, 3, 4, 5]
numbers[1] = ['a','b','c'] 
print(numbers) 

numbers = [1, 2, 3, 4, 5]
numbers[1:2] = ['a','b','c'] 
print(numbers) 

numbers = [1, 2, 3, 4, 5]
numbers[1:3] = ['a','b','c'] 
print(numbers) 

numbers = [1, 2, 3, 4, 5]
numbers[1:4] = ['a','b','c'] 
print(numbers)
