Part 2 Python
This document provides an introduction to Python programming. It discusses that Python is a popular general-purpose programming language created by Guido van Rossum in 1980. It is used for web development, artificial intelligence, and software development. The document then covers setting up the Python environment, variables, data types, control flow, functions, object-oriented programming and classes.

- 20. Introduction to AIwith ML Variables You can think of variable as a little box or a container to store data in the memory of the computer and later retrieve the data using the variable “name” Programmers get to choose the names of the variables You can change the contents of a variable in a later statement

Because comments do not execute, when you run a program you will not see any indication of the comment there. Comments are in the source code for humans to read, not for computers to execute.

We humans understand by keeping things in order that we separate the things that we possess into categories and assign fixed locations to these categories that we can remember. • We may simply throw socks into a drawer, but for other things like DVDs it is best to sort them beyond a certain number so that we can quickly find every DVD.

- 36. Introduction to AIwith ML 07:Data Structures There are four collection data types in the Python programming language: List is a collection which is ordered and changeable. Allows duplicate members. Tuple is a collection which is ordered and unchangeable. Allows duplicate members. Set is a collection which is unordered and unindexed. No duplicate members. Dictionary is a collection which is ordered* and changeable. No duplicate members.
- 37. Introduction to AIwith ML 07:Data Structures-List Lists are used to store multiple items in a single variable. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage. The list is changeable, meaning that we can change, add, and remove items in a list after it has been created. Lists are created using square brackets:
- 38. Introduction to AIwith ML 07:Data Structures-Tuples Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable. Tuples are written with round brackets.
- 39. Introduction to AIwith ML 07:Data Structures-Sets Sets are used to store multiple items in a single variable. Set is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Tuple, and Dictionary, all with different qualities and usage. A set is a collection which is both unordered and unindexed. Sets are written with curly brackets.
- 40. Introduction to AIwith ML 07:Data Structures-Sets You cannot access items in a set by referring to an index or a key. But you can loop through the set items using a for loop, or ask if a specified value is present in a set, by using the in keyword. Once a set is created, you cannot change its items, but you can add new items. To add one item to a set use the add() method. To remove an item in a set, use the remove(), or the discard() method.

- 42. Introduction to AIwith ML 07:Data Structures-DICT Dictionaries are used to store data values in key:value pairs. A dictionary is a collection which is ordered*, changeable and does not allow duplicates. We use it to create JSON APIS.
- 43. Introduction to AIwith ML 07:Data Structures-DICT You can access the items of a dictionary by referring to its key name, inside square brackets: Update the "year" of the car by using the update() method:
- 44. Introduction to AIwith ML 07:Pandas data frame The Pandas DataFrame is a structure that contains two-dimensional data and its corresponding labels. DataFrames are widely used in data science, machine learning, scientific computing, and many other data-intensive fields. DataFrames are similar to SQL tables or the spreadsheets that you work with in Excel or Calc.

- 46. Introduction to AIwith ML 08:Functions A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. A function can return data as a result.
- 47. Introduction to AIwith ML 09:Object Oriented Programming Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods).

This saves time, improves the features in your program, and generally makes for more cost-effective programming. Reusability is an important issue in software engineering.
