list1 = [1,2]
list1 = [3,4]
concat_list1 = list1 + list2 # [1,2,3,4]
concat_list2 = list1.extend(list2) # [1,2,3,4]
concat_list3 = list1.append(list2) # [1,2,[3,4]] <-- list2 is considered 1 element

python concatenate lists

Comment

""" There are 3 methods: '+', list.append, list.extend() """

# '+'
list_one = [11, 12, 13]
list_two = [14, 15, 16]
answer = list_one + list_two
--> answer: [11,12,13,14,15,16]

# 'list.append'  adds items indivudually
# WARNING it treats a list as 1 item
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.append(second_list)
--> first_list: [1, 2, 3, 4, 5, [6, 7, 8, 9]]

# 'extend'  adds to the end, only works when both are lists
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.extend(second_list)
--> first_list: [1, 2, 3, 4, 5, 6, 7, 8, 9]

test_list2 = ['p', 'q', 'r', 's']
for i in test_list2 :
    test_list1.append(i)
print(test_list1)

# Method 02
test_list1 = [1, 4, 5, 6, 5]
test_list2 = ['p', 'q', 'r', 's']
test_list3 = test_list1 + test_list2
print(test_list3)

# Method 03
test_list1 = [1, 4, 5, 6, 5]
test_list2 = ['p', 'q', 'r', 's']
res_list = [y for x in [test_list1, test_list2] for y in x]
print(res_list)

# Method 04
test_list1 = [1, 4, 5, 6, 5]
test_list2 = ['p', 'q', 'r', 's']
