List Data Structure in 5 mins - Python

Hi developers/learners/readers 🙋‍♀️✋

Python Unleashed 07

Going to do comparison between C++ vectors and Python lists in this blog. As I am moving to Python from C++, so this can help others like me.

To those who are not familiar with C++, you may find few things confusing.

INTRO

• List items are within square brackets, like C++ arrays/vector
• Dynamically sized, can shrink and grow
• elements are separated by comma as always
• Stores data in sequence, in linear fashion
• It can store data of any type, unlike vectors in C++
• Random Access Possible (Negative and Positive Index), Prone to Index out of bound errors, AND ZERO BASED INDEXING
• Mutable
• We do have a list class for lists

List is so so much similar to vectors.

list[-0] returns 0th elements only

Methods on List

1. Append -> add element to the end of list, one at a time, tuple and lists can be added

1. Insert -> requires two values, element can be added at desired position. One argument is position, second is value.

1. Extend -> add multiple elements to the end of list, elements must be in square bracket.

1. Reverse -> reverses the list

1. Reversed -> A good read

2. Remove Elements -> Removes one element at a time, and element must be there in the list, otherwise throws error, pass element which you would like to delete

1. Pop -> Either remove element from end only or pass index

2. Slicing -> Same as that for strings check here strings

Heyo — cool post here!

Just a heads up that you can write your code in code blocks with syntax highlighting if you'd like. This will make it easier for folks to copy and run your code.

To do so, you just need to enclose your code with three back ticks before and after + make sure to specify the name of the language to enable syntax highlighting.

For example, writing this:

... will create this:

console.log(`something`)

Hope this helps! More details in our editor guide!

thanks a lot! will start this for my next blogs

Instead of images from carbon or using code highlighting there is one more interactive way to show the code with preview and code runner. So that people can also edit and see the results for satisfaction and clarity.
