Keywords in Python | Python reserved words

Keywords in Python are pre-defined and reserved words. These words are defined by the Python creator. Every keyword has its own meaning and is defined to perform a particular task.

For example, the "if" keyword is used to allow the program to make a decision based on the given or certain conditions. Consider the following code as an illustration.

x = 10
y = 20

if x < y:
    print("The value of 'x' is less than the value of 'y'.")

The output should be:

The value of 'x' is less than the value of 'y'.

Because the value of "x" (10) is less than the value of "y" (20) in the above program, the condition "x < y" is true, and the "print()" statement or function was executed.

Keywords define the syntax and structure of the code and cannot be used as variable, function, or class names. A syntax error will result from doing so.
