📗Python Definitions

Python, being a dynamically typed language, offers a variety of value types (data types) and keywords that are integral to its programming structure. Here's a list of some common value types and keywords along with their definitions:

Value Types (Data Types)

1. int: Represents integer values. Example: 5, -3.

2. float: Represents floating-point numbers (decimals). Example: 3.14, -0.001.

3. str: String type for text. Example: "Hello", 'Python'.

4. bool: Boolean type, representing True or False.

5. list: An ordered, mutable (changeable) collection of items. Example: [1, 2, 3], ['a', 'b', 'c'].

6. tuple: An ordered, immutable collection of items. Example: (1, 2, 3), ('a', 'b', 'c').

7. dict: Dictionary type, an unordered collection of key-value pairs. Example: {'name': 'Alice', 'age': 25}.

8. set: An unordered collection of unique items. Example: {1, 2, 3}.

9. NoneType: Special type representing the absence of a value or a null value. Example: None.

Keywords

1. def: Used to define a function. Example: def my_function():.

2. return: Used to return a value from a function.

3. class: Used to define a class.

4. import, from: Used to import modules or specific functions, classes, etc., from modules.

5. as: Used in import statements to give an imported module a different alias, or with try...except blocks to rename exceptions.

6. if, elif, else: Conditional statements.

7. for, while: Loop control statements.

8. break: Exits a loop.

9. continue: Skips the current iteration in a loop.

10. try, except, finally, raise: Exception handling keywords.

11. with: Used for exception handling in resource management (like file reading/writing).

12. global: Declares a variable as global.

13. nonlocal: Declares a variable as non-local (useful in nested functions).

14. lambda: Used to create an anonymous function.

15. yield: Used in a function like return, but for generator functions.

16. del: Deletes an object.

17. pass: A null statement, a placeholder for future code.

18. assert: Used for debugging purposes to check conditions that should always be True.

19. in, not in: Membership operators.

20. is, is not: Identity operators.
