Example 1: append element to an array python

Example 2: python append vs extend

my_list = [23, 11, 42, 24523]

# append will add it as if you're adding a new list to it
my_list.append([34523, 76979])
print(my_list)

# extend will go over each item in the new source list and add each
# element as part of the target list (my_list)
my_list.extend([12, 99])
print(my_list)

""" 
Output:
[23, 11, 42, 24523, [34523, 76979]]
[23, 11, 42, 24523, [34523, 76979], 12, 99]
"""

Example 3: python array append

my_list.append(other_list) 
print(my_list)      # ['a','b','c',[1,2]]

Example 5: append python

List = ["One", "value"]

List.append("to add") # "to add" can also be an int, a foat or whatever"

#List is now ["One", "value","to add"]

#Or

List2 = ["One", "value"]
# "to add" can be any type but IT MUST be in a list
List2 += ["to add"] # can be seen as List2 = List2 + ["to add"]

#List2 is now ["One", "value", "to add"]
