Keywords
True keyword is used as the Boolean true value, in Python code.
Python keywords are special reserved words with specific meanings and purposes and cannot be used for anything but those specific purposes. These keywords are always available — you ’ll no way have to import them into your law. Python keywords are the abecedarian structure blocks of any Python program.
The Python keyword False is analogous to the True keyword, but with the contrary Boolean value of false.
Difference between Keywords and Identifiers
Keywords are distinct; they aren't further classified. On the negative, if identifiers are involved in an external link process, i.e. However, also it's called ‘external names’, while they aren't used in external link process and include the name of original variable, if it includes function names and global variable that are participated between lines.
The identifier can noway be same as keywords, and the name of functions that are in C library.
Keywords defined in C library doesn't contain any symbol. Again, when you declare any identifier, you can only use underscore but not any other symbol.
When writing the program, it's important to give meaningful names as it improves law readability. Thus, the programmer can produce names to identify them. They're known as identifiers. An identifier is a stoner defined name given to a variable, function, array or class. There's also a set of words handed by the programming language having specific meanings.
They're known as keywords. Keywords belong to the language, and each have particular tasks. These keywords can not be used as identifier names. This composition discusses the difference between an identifier and a keyword.
Difference Between Variable and Identifier
Variable is only a kind of identifier, other kinds of identifiers are function names, class names, structure names, etc. So, it can be said that all variables are identifiers whereas, vice versa isn't true.
As identifier and variable names are stoner- defined names, it should be taken care that no two identifiers or no two variable names in a program should be the same. It'll produce a problem of nebulosity in a program.
In this article we will talk about the Keywords, identifiers and Variables.KeywordsPython IDEs can be used to highlight keywords to differentiate them from other words in your code.
This IDEs will help you to quickly identify Python keywords so you don’t use them incorrectly in programming.In Python code, True keyword is used as the Boolean true value.Python keywords are special reserved words that have specific meanings and purposes and ca not be used for anything but those specific purposes.

Identifiers An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique class of objects, where the" object “or class may be an idea, physical innumerable object (or class thereof), or physical noncountable substance (or class thereof).As the name says, identifiers are used to identify a particular element in a program.Though these are hard rules for writing identifiers, also there are some picking conventions which aren't obligatory but rather good practices to follow.
All other identifiers start with a lowercase letter.Starting an identifier with a single leading underscore indicates the identifier is private.Still, then means the identifier is language- defined special name, If the identifier starts and ends with two underscores.While c = 10 is valid, writing count = 10 would make further sense and it would be easier to figure out what it does indeed when you look at your law after a long time.
