#Python #Tutorial #Lists

Python Tutorial: Python list is a data structure that stores items (i.e. integer and string ) into memory. Lists in Python are more powerful and versatile than an array. Python lists are the most widely used python sequence.

Lists in python are like an array of C, JAVA, COBOL. But, there is two major difference between an array and a Python list.

1. In Lists, you can store different types of elements at the same time. But in the array, you can store only similar items.
2. Lists in Python can expand dynamically. But an array cannot expand. You have to define the size of any array explicitly.

In this Python tutorial on lists, you will learn the basic concept of Lists and various built-in functions. You'll also learn about various lists methods with live code demo.

List Built-in Function:

1. Min Function.
2. Max Function.
3. Len Function
4. Count Function

List of Built-in Methods: Following are a couple of lists methods.

1. List Append Python: To append a value to list.
2. List Index Python: To get an index of value from the list.
3. List Sum Python: To get the sum of list items.
4. List Reverse Python: To reverse order of an item in lists.
5. List Insert Python: To insert an item at a specific position in the list.
6. List Sort Python: To sort item of the list.
8. List Pop Python: To drop the last element from the list.
9. List Remove Python: Remove specific element from the list.

In a live code demo, you will learn the practical implementation of all built-in function and methods. The demo cover following list code example:

1. How to define the list in Python.
2. How to use the built-in function to manipulate data in Python Lists.
3. Python List comprehension:
4. How to define a list with Python range function.
5. How to calculate the square of all even number in the lists.
6. How to calculate the square of all odd numbers in the lists.
7. How to print list item using Python for a loop.
8. How to concatenate two lists in Python.
9. How to clear items off the list.

Summary: Finally, a list in Python represents a group of elements. They are powerful and easy to use data structure in programs. You can use various built-in function and methods to manipulate lists items.
