🚀 Day 56/150 – Merge Two Lists in Python

Merging lists means combining elements from two lists into one.

Python gives multiple simple ways to do it depending on whether you want a new list or want to modify the existing list.

🔹 Method 1 – Using + Operator

list1 = [1, 2, 3] list2 = [4, 5, 6] merged = list1 + list2 print("Merged List:", merged)

🔹 Method 2 – Using extend()

list1 = [1, 2, 3]
list2 = [4, 5, 6]

list1.extend(list2)

print("Merged List:", list1)

🔹 Method 3 – Using Loop

list1 = [1, 2, 3] list2 = [4, 5, 6] merged = list1.copy() for num in list2: merged.append(num) print("Merged List:", merged)

🔹 Method 4 – Taking User Input

list1 = list(map(int, input("Enter first list: ").split()))

list2 = list(map(int, input("Enter second list: ").split()))

merged = list1 + list2

print("Merged List:", merged)

💡 Key Takeaways

• + creates a new merged list
• extend() changes the original list
• Loop + append() helps understand how merging works internally
• Very useful before sorting, searching, or removing duplicates
