Joining Lists in Python

There are many ways to join or merge Python lists such as using + operator, extend(), append(), and list comprehension.

Python में दो या अधिक lists को जोड़ने के कई तरीके होते हैं जैसे + ऑपरेटर, extend(), append() और list comprehension।

1. Using + Operator

list1 = ["abhishek", "badri"]
list2 = ["devendra", "chandrakant"]
result = list1 + list2
print(result)

Output:

['abhishek', 'badri', 'devendra', 'chandrakant']

2. Using extend()

list1 = ["abhishek", "badri"]
list2 = ["devendra", "chandrakant"]
list1.extend(list2)
print(list1)

Output:

['abhishek', 'badri', 'devendra', 'chandrakant']

3. Using append() in a loop

list1 = ["abhishek", "badri"]
list2 = ["devendra", "chandrakant"]
for name in list2:
    list1.append(name)
print(list1)

Output:

['abhishek', 'badri', 'devendra', 'chandrakant']

4. Using list comprehension

list1 = ["abhishek", "badri"]
list2 = ["devendra", "chandrakant"]
result = [name for name in list1] + [name for name in list2]
print(result)

Output:

['abhishek', 'badri', 'devendra', 'chandrakant']

5. Using unpacking *

list1 = ["abhishek", "badri"]
list2 = ["devendra", "chandrakant"]
result = [*list1, *list2]
print(result)

Output:

['abhishek', 'badri', 'devendra', 'chandrakant']
