Each programming language has its own set of keywords, much like every spoken language has its own set of words. Python, like most other contemporary programming languages, makes extensive use of all of its keywords. The iteration control structures if, else, while, for, break, etc. are commonplace in high-level programming languages. Python’s “reserved keywords” are another name for these terms. all keywords in python are in have defined functions in the context of computer programming. Keywords carry no significance. Variables hold the value. Identifiers are names for classes, methods, and variables. In this lesson, you will learn the fundamentals of Python’s keyword and identifier syntax.
Search terms (Reserved words)
Python is a case-sensitive programming language, therefore it seems sensible that its reserved names would be as well. Python keywords are reserved due to their purpose and scope. Restricted terms are unambiguous. Using reserved phrases properly is the most important consideration. Changing the case of banned words changes their meaning. The word is now acceptable. This graphic shows Python-reserved phrases. Python supports 33 non-standard characters that have no equivalent in English. Integer, floating-point, import, if, elif, True, False, None, etc. are only a few instances of data types. All python keywords are lowercase except None, True, and False. Let’s start by looking at some key terms:
- Boolean values in Python can only take on the values True and False. These numbers all have equal potential to express the conclusion of the reasoning.
- Logical operators like and, or, and not being supported in Python. The output of these operations is always a Boolean value.
- Decision control keywords include if, elif, and else; loop control keywords include while, for, break, and continue; and if you want to exit the loop or keep going through the current iteration, you use the terms while and for in the while statement. Using this keyword, you can create a class that serves a certain purpose.
- Defines a user-defined function.
- “expect,” “try,” and “raise” are python keywords used in exception handling, which deals with code errors. If you need Python’s built-in modules, use the import keyword. The global keyword allows outside access to a function’s variable.
Typical examples of Python-reserved keywords are provided below. Example search terms are as follows:
This illustration makes use of the following notation and variables: int, for, in, def, if, or, else, True, and False.
First, let’s talk about Identifiers.
Identifiers
In Python, identifiers are the names you give entities like variables, classes, and functions. The application will immediately crash if we try to use keywords as identifiers. There is a standard that Python names must follow. Order, they are as follows:
- An all-alphanumeric identification may have one underscore ( ). Student Name 1 is an example of an acceptable identification name.
- In Python, many forms of capitalization have specific meanings. The identifier’s name and the NAME will be handled independently, for instance.
- The identifying process cannot have any gaps in it. Using “student name” as the name of a variable is an inappropriate example. You can also use the format student name instead.
- The initial character of an identifier must always be a letter or an underscore. A number cannot be the initial identifier in a number sequence. Name1, or _name1, both of which are acceptable identifiers in Python, are not acceptable, nor is 1name.
- A length d’s is unbounded.
Now let’s have a look at some actual Python names:
identifiers include: a-b-2-1-g-labeled listings (this is a name given to a function)

Summary
Keywords and identifiers in Python have been discussed. There is a distinction between a keyword and an identifier in Python, and we are familiar with both. all keywords in python are in must be capitalized since the language treats them as such. Well-defined Python keyword IDs are useful. Class, variable, and method names are identifiers. It is not possible to utilize keywords as identifiers at this time. Python has requirements for valid names and identifiers. We have finished our survey of Python keywords and identifiers.
