how to update list in python

simple_list = [1,2,3,4]

# append an element
simple_list.append(5) # now simple_list is [1,2,3,4,5]

# append all the elements of another list (NO NESTING)
second_list = [6,7,8]
simple_list.extend(second_list) # now simple_list is [1,2,3,4,5,6,7,8]

# replace an element by simply giving the index and the new element
simple_list[0] = 100 # now simple_list is [100,2,3,4,5,6,7,8]

python get element from list

my_list = ["pizza", "soda", "muffins"]

my_list[0] # outputs "pizza"
my_list[-1] # outputs the last element of the list which is "muffins"
my_list[:] # outputs the whole list
my_list[:-1] # outputs the whole list except its last element

# you can also access a string's letter like this

python get element by index

# To return the index of the first occurence of element x in lst
ind = lst.index(x)
