Document 对象参考手册Python3 Examples

In Python, merging two lists into one can be achieved in multiple ways. The most common method is to use the+operator orextend()method. Below is a simple example showing how to merge two lists into one.

Example

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

# Use the + operator to merge lists
merged_list = list1 + list2

print("Merged list:", merged_list)

Code explanation:

  • list1andlist2are the two lists to be merged.
  • merged_list = list1 + list2Use the+operator tolist1andlist2merge into a new listmerged_list。
  • print("合并后的列表:", merged_list)Print the merged list.

Output result:

合并后的列表: [1, 2, 3, 4, 5, 6]

You can also use theextend()method to merge lists, as shown below:

Code section:

Example

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

# Use the extend() method to merge lists
list1.extend(list2)

print("Merged list:", list1)

Code explanation:

  • list1.extend(list2)willlist2elements from are added tolist1the end of.
  • print("合并后的列表:", list1)Print the merged list.

Output result:

合并后的列表: [1, 2, 3, 4, 5, 6]

Both methods can effectively merge two lists. Which method you choose depends on your specific needs.
