Python Join Lists

Join Two Lists

In Python, you can join lists using various methods depending on what exactly you want to achieve.

Using the + operator:

You can concatenate two lists using the + operator.

list1 = [1, 2, 3]
list2 = [4, 5, 6]
joined_list = list1 + list2
print(joined_list)
                 
             

Using the extend() method:

This method adds elements of a list (or any iterable) to the end of the current list.

list1 = [1, 2, 3]
list2 = [4, 5, 6]
list1.extend = (list2)
print(list1)
 
             

Using list comprehension:

You can also use list comprehension to join lists.

list1 = [1, 2, 3]
list2 = [4, 5, 6]
joined_list = [x for x in list1] + [x for x in list2]
print(joined_list)

                
             

Using the append() method in a loop:

You can iterate over one list and append its elements to another list.

list1 = [1, 2, 3]
list2 = [4, 5, 6]
 for item in list2:
  list1.append(item)
print(list1)
