Keywords and Identifiers in Python

Keywords and Identifiers in Python

Every language has keywords and identifiers, which are only concluded by its compiler. Keywords are predefined reserved words, which hold special meaning. Each keyword defines the “ type” declared data. Keywords shouldn't be used as identifiers. An identifier is a special name given to a particular variable, function or tag of class in the program. To produce a variable, both a keyword and an identifier are chain together.

The identifiers can be altered if needed, while this isn't the case with keywords, which are fixed, we can't modify it according to our want. This content beyond elaborates the distinction between a keyword and an identifier.

Keywords

Keywords are basically featured in IDE when you write a code. This will assist you identify Python keywords while you ’re writing a code so you do n’t use them improperly.

Keywords are the reserved words in python. These reserved words can not be applied as function name, variable name or any other identifier.

Keywords are special words that have a especial aim. They're commonly applied to define the syntax and structure of a program.

Identifiers

Identifiers in python are the names that we choose for custom variables, functions, or classes in a python program.

In Python, an identifier is a name applied to identify a variable, function, class, module or other objects. Identifier begins with a letter a to z or A to Z or an underscore (,) tracked by zero or further letters, underscores, and integers (0 to 9). An identifier is a name given to individuals like class, functions, variables etc. in Python. It helps to difference one reality from another.

· An identifier can be of any length, still, it's always good to make it shorter to make it more readable.

· Class names start with an uppercase letter. All other identifiers start with a lowercase letter.

· Starting an identifier with a single directing underscore indicates that the identifier is private.

· Starting an identifier with two leading underscores indicates a firmly private identifier.

· Still, the identifier is a language- defined special name, If the identifier also ends with two following underscores.
