python tutorial - Python with Keyword | Python Keywords - learn python - python programming

Keywords are special reserved words which convey a special meaning to the compiler/interpreter.

Each keyword have a special meaning and a specific operation.
Keywords are the reserved words in Python.
We cannot use a keyword as variable name, function name or any other identifier. They are used to define the syntax and structure of the Python language.
In Python, keywords are case sensitive.
There are 33 keywords in Python 3.3. This number can vary slightly in course of time.
All the keywords except True, False and None are in lowercase and they must be written as it is. The list of all the keywords are given below.
The following is a list of keywords for the Python programming language. and del from not while as elif global or with assert else if pass yield break except import print class exec in raise continue finally is return def for lambda try.
Python is a dynamic language. It changes during time.
Here are simple rules to define a function in Python. Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ).
Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.

Keywords Explained:

print	print to console
while	controlling the flow of the program
for	iterate over items of a collection in order that they appear
break	interrupt the (loop) cycle, if needed
if	used to determine, which statements are going to be executed.
continue	used to interrupt the current cycle, without jumping out of the whole cycle. New cycle will begin.

else	is optional. The statement after the else keyword is executed, unless the condition is True
is	tests for object identity
not	negates a boolean value
and	all conditions in a boolean expression must be met
or	at least one condition must be met.
import	import other modules into a Python script
as	if we want to give a module a different alias
from	for importing a specific variable, class or a function from a module
def	used to create a new user defined function
return	exits the function and returns a value
lambda	creates a new anonymous function
global	access variables defined outside functions
try	specifies exception handlers
except	catches the exception and executes codes
finally	is always executed in the end. Used to clean up resources.
raise	create a user defined exception
del	deletes objects
pass	does nothing
assert	used for debugging purposes
class	used to create new user defined objects
exec	executes Python code dynamically
yield	is used with generators.
