Keywords. Python has a set of keywords that are reserved words that cannot be used as variable names, function names, or any other identifiers: Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.

- Value Keywords: True, False, None. There are three Python keywords that are used as values. These values are singleton values that can be used over and over again and always reference the exact same object.
- Operator Keywords: and, or, not, in, is. Several Python keywords are used as operators. In other programming languages, these operators use symbols like &, |, and !.
- Control Flow Keywords: if, elif, else. Three Python keywords are used for control flow: if, elif, and else. These Python keywords allow you to use conditional logic and execute code given certain conditions.
- Iteration Keywords: for, while, break, continue, else. Looping and iteration are hugely important programming concepts. Several Python keywords are used to create and work with loops.

Getting the List of all Python keywords
We can also get all the keyword names using the below code. Output: Let’s discuss each keyword in detail with the help of good examples.
True:This keyword is used to represent a boolean true. If a statement is true, “True” is printed.False: This keyword is used to represent a boolean false. If a statement is false, “False” is printed.None:This is a special constant used to denote a null value or a void. It’s important to remember, 0, any empty container(e.g. empty list) does not compute to None. It is an object of its datatype...Python and Keyword
This a logical operator in Python. “and” Return the first false value. If not found return last. The truth table for “and” is depicted below. 3 and 0 return 0 3 and 10 return 10 10 or 20 or 30 or 10 or 70 returns 10 The above statements might be a bit confusing to a programmer coming from a language like Cwhere the logical operators always return boolean values(0 or 1). The following lines are straight from the Pythondocsexplaining this: Notethat neither and nor restrict the value and type th...
Python or Keyword
This a logical operator in Python. “or” Return the first True value. if not found return last. The truth table for “or” is depicted below. 1. not: This logical operator inverts the truth value. The truth table for “not” is depicted below. 2. in:This keyword is used to check if a container contains a value. This keyword is also used to loop through the container. 3. is:This keyword is used to test object identity, i.e to check if both the objects take the same memory location or not.
and, or, not, is and in keyword implementation in Python
The provided code demonstrates various Python operations: 1. Logical Operations: 1.1. 'or'returns ‘True'when at least one operand is ‘True'. 1.2. 'and'returns ‘True'only when both operands are ‘True'. 1.3. 'not'negates the operand. 2. Python “in” Keyword: 2.1. It checks if ‘s’ is in the string ‘geeksforgeeks’ and prints accordingly. 2.2. It loops through the string’s characters. 3. Python “is” Keyword: 3.1. It checks if two empty strings (‘ ‘) are identical (returns ‘True'). 3.2. It checks if...
if : It is a control statement for decision making. Truth expression forces control to go in “if” statement block.else : It is a control statement for decision making. False expression forces control to go in “else” statement block.elif: It is a control statement for decision making. It is short for “else if“Python def
def keyword is used to declare user defined functions.
class in Python
classkeyword is used to declare user defined classes.
With in Python
withkeyword is used to wrap the execution of block of code within methods defined by context manager. This keyword is not used much in day to day programming.
import: This statement is used to include a particular module into current program. from :Generally used with import, from is used to import particular functionality from the module imported.
raise: We can raise an exception explicitly with the raise keyword- True keyword. The True in python is used to define true values. If a given condition is true then python returns True. To check truthy value of a variable in Python, use the bool() function.
- False keyword. The False in python is used to define false values. If a given condition is false then python returns False. Python uses False, not false to define falsy values.
- None keyword. The None keyword is used to define the null value in Python. (null means no value) None value doesn't define 0 or '' (empty string), it just means nothing is there.
- and keyword. The and keyword in python determines the truth value of the operands. If both of the operands are truthy then it returns a truthy value, else returns falsy.
- Value Keywords: True, False, None. True and False are used to represent truth values, know as boolean values. It is used with a conditional statement to determine which block of code to execute.
- Operator Keywords: and, or, not, in, is. The logical and keyword returns True if both expressions are True. Otherwise, it will return. False. The logical or keyword returns a boolean True if one expression is true, and it returns False if both values are false.
- Conditional Keywords: if, elif, else. In Python, condition keywords act depending on whether a given condition is true or false. You can execute different blocks of codes depending on the outcome of a condition.
- Iterative and Transfer Keywords: for, while, break, continue, else. Iterative keywords allow us to execute a block of code repeatedly. We also call it a loop statements.
Aug 13, 2024 · Keywords in Python are reserved words that have special meanings and purposes. These words cannot be used as identifiers (variable names, function names, class names, etc.) because they are used to define the syntax and structure of the Python language itself.
