Which of the following is a python keyword?
Keywords are the reserved words in Python. We cannot use a keyword as a variable name, function name or any other identifier. Show Here's a list of all keywords in Python Programming Keywords in Python programming language
The above keywords may get altered in different versions of Python. Some extra might get added or some might be removed. You can always get the list of keywords in your current version by typing the following in the prompt.

Here we imported the assert
While programming, sometimes we wish to know the internal state or check if our assumptions are true. If the condition is true, nothing happens. But if the condition is false,
For our better understanding, we can also provide a message to be printed with the

To run the program, we use
In the above program, the Here, first Hello is printed. The break, continue
This can be illustrated with the following two examples:

Class is a collection of related attributes and methods that try to represent a real-world situation. This idea of putting data and functions together in a class is central to the concept of object-oriented programming (OOP). Classes can be defined anywhere in a program. But it is a good practice to define a single class in a module. Following is a sample usage:

Here we can see that the reference of the variable a was deleted. So, it is no longer defined. But b still exists.

When we want to test some condition and execute a block only if the condition is true, then we use

Exceptions are basically errors that suggests something went wrong while executing our program. We can raise an exception explicitly with the

If we need to read the value of a global variable, it is
not necessary to define it as If we need to modify the value of a global variable inside a function, then we must declare it with Following example will help us clarify this.

An empty list or dictionary is equal to another empty one. But they are not identical objects as they are located separately in memory. This is because list and dictionary are mutable (value can be changed).
Unlike list and dictionary, string and tuple are immutable (value cannot be altered once defined). Hence, two equal string or tuple are identical as well. They refer to the same memory location. lambda

These keywords are always available—you'll never have to import them into your code. Python keywords are different from Python's built-in functions and types.
Which of the following is not a Python keyword?1 Answer. The correct answer to the question “Which of the following is not a Keyword in Python” is option (a). Val. As Val is not a correct keyword, in Python and all others are keywords.
Is or a keyword in Python?Definition and Usage
The or keyword is a logical operator. Logical operators are used to combine conditional statements. The return value will be True if one of the statements return True , otherwise it will return False .
