One of the easiest ways are by using the +
operator.

list3 = list1 + list2
print(list3)

list2 = [1, 2, 3]
list3 = list1 + list2
print(list3)
Another way to join two lists are by appending all the items from list2 into list1, one by one:
Example
Append list2 into list1:
list1 = ["a", "b" , "c"]
list2 = [1, 2, 3]
for x in list2:
list1.append(x)
print(list1)
Try it Yourself »
list2 = [1, 2, 3]
for x in list2:
list1.append(x)
print(list1)
Or you can use the extend()
method,
which purpose is to add elements from one list to another
list:
Example
Use the extend() method to add list2 at the end of list1:
list1 = ["a", "b" , "c"]
list2 = [1, 2, 3]
list1.extend(list2)
print(list1)
Try it Yourself »
list2 = [1, 2, 3]
list1.extend(list2)
print(list1)
