Basic – syntax Of Python ..
python programming language have many similar things to c, Perl and java but the python has much big difference to compare with those, python is easy to compare with java or c you have to writ some code which has 50 lines but in python that is completed into 20 to 25 lines
Let execute one simple program in different ways
Interactive Mode Programming
iterative mode programming is a CMD (command-line shell )which gives instant reply or output for each statement while running previously fed statement inactive memory when you have to just perform the basic operation or basic python code then generally this mode is used.
if you are using python version series 3.0. something then you have to perform below code
if you are using python version series 2.0. something then you have to perform below code
print "hello world"
Output of above code is same for both version just in 2.0 there are no braces

Script Mode Programming
Invoking the interpreter with a script parameter starts the execution of the script and maintains till the script is finished. When the script is finished, the interpreter is no longer lively.
print "Hello world"
we assume you have set the interpreter of python as a PATH variable now when you write code as above and save as test1.py for a run this file you have to code like below, you have to write below code in CMD
$ python test.py
After Running this above then you get output like below
a python identifier which is the user to give a name to variable, class, method, function, and object of the class. this method is basically for which type of name you can give.
this is saying if you want to give a name you have to start with A to Z or a to z or an underscore ( _ ) followed by zero or more digits ( 0 to 9 ).
In this python say you don’t have to use special characters such as @, $ and %
Python is a case sensitive language means when you define one variable with name School and one with school then both are different.
Reserved words of python
The below list of keywords are already reserved by python you do not use this for declaring a class, variable or method you don’t use the same name suppose we have one keyword global so, we do not use to declare a class variable or anything there are some reserved keyword list is below.
