Python Keywords

Python keywords are reserved words that have predefined meanings. The Python Interpreter uses keywords to understand the program. Python uses several keywords that cannot be used as identifiers. Python does not allow the use of a keyword as a variable name, function name, etc. Keywords in Python language are case-sensitive.

Python Keywords

The keywords may get altered in different versions of Python. We can get the list of keywords in our current version by typing the following in the prompt.

False	class	from	or
None	continue	global	pass
True	def	if	raise
and	del	import	return
as	elif	in	try
assert	else	is	while
async	except	lambda	with
await	finally	nonlocal	yield
break	for	not

We can get the complete list of keywords using the Python interpreter help utility. There are 35 keywords in the Python 3.x release.

Type help() for interactive help at the Python interpreter prompt.

>>> help()

To get a list of available keywords, type keywords

Python Keywords

Each keyword in Python language has a specific function and is integral to the structure of a Python program.

Python Keyword	Description
False	The False keyword represents the boolean false value.
None	The None keyword represents the absence of a value or a null value.
True	The True value represents the boolean true value.
and	The and is a logical operator used to combine conditional expressions.
as	The as keyword is used to create an alias while importing a Python module.
assert	The assert keyword is used for debugging purposes.
async	The async keyword is used to declare an asynchronous function.
await	The await keyword is used to wait for the completion of an asynchronous function.
break	The break keyword is used to break out of a loop.
class	The class keyword is used to define a new class in Python.
continue	The continue skips the rest of the code inside a loop for the current iteration only.
def	The def keyword is used to define a function.
del	del keyword is used to delete a reference to an object.
elif	The elif is used in conditional statements, same as else if.
else	else is used in conditional statements.
except	except keyword is used with exceptions, what to do when an exception occurs.
finally	The finally keyword is used with exceptions, a block of code that will be executed no matter if there is an exception or not.
for	The for keyword is used for looping, typically used with the in keyword.
from	from keyword is used to import specific parts of a module.
global	The global is used to declare a global variable.
if	if is used for conditional branching.
import	import keyword is used to import a module.
in	in checks if a value is present in a Python data structure like list, tuple, etc.
is	is tests for object identity.
lambda	The lambda keyword is used to create an anonymous function.
nonlocal	nonlocal declares a non-local variable.
not	not is a logical operator used to invert the truth value.
or	or is a logical operator used to combine conditional expressions.
pass	The pass is a placeholder for a null statement.
raise	raise keyword is used to raise an exception.
return	return is used to exit a function and return a value.
try	try is used to specify exception handlers and/or cleanup code for a group of statements.
while	The while keyword is used for looping.
with	with keyword is used to wrap the execution of a block of code.
yield	The yield keyword ends a function and returns a generator.

The keywords have special meanings and are part of the syntax of the Python language. These keywords provide the basic structure and control flow mechanisms in Python programming.
