Python Keywords:
Keywords are the reserved words in Python. We cannot use a keyword as variable name, function name or any other identifier.
Here's a list of all keywords in Python Programming
1. None : None is a special constant in Python that represents the absence of a value or a null value.
2. and, or , not : and, or, not are the logical operators in Python. and will result into True only if both the operands are True.
3. As : as is used to create an alias while importing a module. It means giving a different name (user-defined) to a module while importing it.
4. Assert : assert is used for debugging purposes.
5. break, continue : break and continue are used inside for and while loops to alter their normal behavior.
6. Class : class is used to define a new user-defined class in Python.
7. Def : def is used to define a user-defined function.
8. Del : del is used to delete the reference to an object. Everything is object in Python. We can delete a variable reference using del
9. if, else, elif : if, else, elif are used for conditional branching or decision making.
10. except, raise, try : except, raise, try are used with exceptions in Python.
11. Finally : finally is used with try…except block to close up resources or file streams.
