A Python program is divided into a number of logical lines.

Physical and logical lines

A physical line is a sequence of characters terminated by an end-of-line sequence. The end of a logical line is represented by the token NEWLINE. A logical line is ignored (i.e. no NEWLINE token is generated) that contains only spaces, tabs, or a comment. This is called "blank line". The following code

An operator is a symbol (such as +, x, etc.) that represents an operation. An operation is an action or procedure which produces a new value from one or more input values called operands. There are two types of operators: unary and binary. Unary operator operates only on one operand, such as negation. On the other hand, binary operator operates on two operands, which includes addition, subtraction, multiplication, division, exponentiation operators etc. Consider an expression 3+8, here 3 and 8 are called operands, while '+' is called operator. The operators can also be categorized into:

If Statement, it is also known as a condition statement. If statement increase the functionality of a Python. The ability to use logic "if-then-else" in your program is one of the most basic and fundamental aspects for programming. Python programming provides an easy way to tell your program what to do if something is true, and what to do if something is false.

Python can manipulate string, which can be expressed in several ways. String literals can be enclosed in matching single quotes(') or double quotes("); e.g. 'hello', "hello" etc. They can also be enclosed in matching groups of three single or double quotes (these are generally referred to as triplequoted strings), e.g.'' 'hello''', """hello""". A string is enclosed in double quotes if the string contains a single quote (and no double quotes), else it is enclosed in single quotes.

Variable is a reserved memory storage location that has an associated symbolic name (called "identifier"), which contains some value (can be literal or other data) that can change. You do not need to declare variables before you use them, or declare its type. An identifier is a name used to identify a variable, function, class, module or other object. Literal is a notation for constant values of some built-in type. Literal can be string, plain integer, long integer, floating point number, imaginary number. All variables in Python are an object. So i create a variable age and name and set that equal to any thing i want. For example

Python is a easy-to-use programming language, both easy to learn and rich in possibilities. It is one of the most interesting programming languages of the time. Python is often used as an example when programming learning. This language was so named in honor the cast of the comic "Monty Python". Python syntax is very simple, code indentation (rather than the use of braces) allows for very readable programs and more compact.
