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
