Python Keywords

Python Keywords

Python Keywords are special reserved words that convey a special meaning to the compiler/interpreter. Each keyword has a special meaning and a specific operation. These keywords can't be used as a variable. Following is the List of Python Keywords.

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

Consider the following explanation of keywords.

1. True - It represents the Boolean true, if the given condition is true, then it returns "True". Non-zero values are treated as true.
2. False - It represents the Boolean false; if the given condition is false, then it returns "False". Zero value is treated as false
3. None - It denotes the null value or void. An empty list or Zero can't be treated as None.
4. and - It is a logical operator. It is used to check the multiple conditions. It returns true if both conditions are true. Consider the following truth table.

A	B	A and B
True	True	True
True	False	False
False	True	False
False	False	False

5. or - It is a logical operator in Python. It returns true if one of the conditions is true. Consider the following truth table.

 

A	B	A and B
True	True	True
True	False	True
False	True	True
False	False	False

6. not - It is a logical operator and inverts the truth value. Consider the following truth table.

A	Not A
True	False
False	True

7. assert - This keyword is used as the debugging tool in Python. It checks the correctness of the code. It raises an AssertionError if found any error in the code and also prints the message with an error.
