Python is a widely used general-purpose, high level programming language. It was created by Guido van Rossum in 1991 and further developed by the Python Software Foundation. It was designed with an emphasis on code readability, and its syntax allows programmers to express their concepts in fewer lines of code. Python is a programming language that lets you work quickly and integrate systems more efficiently.

It's used for

• Web development(Server-side)
• Software Development
• Artificial Intelligence and Machine learning
• System Scripting

LANGUAGE FEATURES

Platform Independent:

Python programs can be developed and executed on multiple operating system platforms. Python can be used on Linux, Windows, Macintosh, Solaris and many more.

Free and Open Source:

Redistributable

High-level Language:

In Python, no need to take care about low-level details such as managing the memory used by the program.

Robust:

Exceptional handling features. Memory management techniques in built

Data types

Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data. Since everything is an object in Python programming, data types are actually classes and variables are instances (object) of these classes. The following are the standard or built-in data types in Python:

• Numeric
• Sequence Type
• Boolean
• Set
• Dictionary
• Binary Types

String

• Strings in python are surrounded by either single quotation marks, or double quotation marks
• 'hello' is the same as "hello".
• You can display a string literal with the print() function

Boolean Values

• In programming you often need to know if an expression is True or False.
• You can evaluate any expression in Python, and get one of two answers, True or False.

Operators

Operators are used to perform operations on variables and value.

Python divides the operators in the following groups:

• Arithmetic operators
• Assignment operators
• Comparison operators
• Logical operators
• Identity operators
• Membership operators
• Bitwise operators

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.

Tuple

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.

Set

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 unordered, unchangeable*, and unindexed

If..Else

Python supports the usual logical conditions from mathematics:

• Equals: a == b
• Not Equals: a != b
• Less than: a < b
• Less than or equal to : a <= b
• Greater than: a > b
• Greater than or equal to: a >= b

These conditions can be used in several ways, most commonly in "if statements" and loops

An "if statement" is written by using the if keyword.
