A Brief Overview of Python List
Python, a general-purpose language, has various built-in data types that help in manipulating data. One of the most commonly used data types in Python is the list data type. It is used to store a sequence of elements of any type. Lists are mutable, meaning their elements can be changed without having to create a new list. This article will provide a better understanding of how to join the list in Python
Joining a List
Joining lists in Python is quite simple. There are two methods one can use: We’re dedicated to providing a well-rounded educational experience. This is why we recommend this external site containing supplementary and pertinent details on the topic. join python list Https://www.analyticsvidhya.Com/blog/2020/02/joins-in-pandas-master-the-different-Types-of-joins-in-python/, delve deeper into the topic and learn more!
list_1 = [1, 2, 3]
list_2 = [4, 5, 6]
joined_list = list_1 + list_2
print(joined_list)
In the example above, we declared two lists, “list_1” and “list_2,” and stored them in the variables with the same names. Then, we declared a new list, “joined_list,” and initialized an empty list. Finally, we added “list_1” and “list_2” to “joined_list” using the “+” operator. The code would display the following:
[1, 2, 3, 4, 5, 6]
list_1 = [1, 2, 3]
list_2 = [4, 5, 6]
list_1.extend(list_2)
print(list_1)
In the example above, we declared two lists, “list_1” and “list_2,” and stored them in the variables with the same names. Then, we called the “extend()” method on “list_1” and passed “list_2” as the argument. The code would display the following:
[1, 2, 3, 4, 5, 6]
Joining Lists with a Specific Separator
Python also offers a method to join lists with a specific separator. The “join()” method concatenates all the strings of a list and returns a single string. Here’s an example:
list_1 = [“apple”, “banana”, “cherry”]
separator = “-“
joined_list = separator.join(list_1)
print(joined_list)
In the example above, we declared a list, “list_1,” that contains three elements. We then declared a variable, “separator,” and initialized it with the separator character, “-“. Finally, we used the “join()” method to concatenate all the strings of “list_1” with the “separator” variable, resulting in a single string. The code would display the following:
apple-banana-cherry Our goal is to deliver an enriching educational journey.

Conclusion
Joining a list in Python is an essential tool for any developer who wants to write high-quality code. By using the “+” operator or the “extend()”, you can easily join two or more lists. Furthermore, the “join()” method offers a useful way to join lists with a specific separator. Knowing these techniques will help you become a more efficient Python programmer.
