What Are All the Keywords Used in Python?
As spoken languages, computer languages have their keywords. Python, like other modern programming languages, uses all its keywords. Words like “if,” “else,” “while,” “for,” “break,” and “continue” are all examples of iteration control structures found in high-level programming languages. Python calls them “reserved keywords”. all keywords in python are in have defined functions in the context of computer programming. Keywords carry no significance. To keep track of the value, developers often utilize variables. There are also names given to entities like classes, methods, and variables; these names are referred to as identifiers. This course introduces Python’s keyword and identifier syntax.
Important phrases (designated words) (Reserved words)
Python is case-sensitive, therefore reserved names should be too. Keywords in Python have a specific meaning and are rarely used, hence they are sometimes referred to as reserved keywords. It is not possible to give the restricted phrases any other meaning.
The proper application of reserved phrases is the single most important consideration. If we alter the case of the prohibited words, the intended meaning no longer holds. The word is now allowed. Python’s collection of reserved phrases is depicted in the following figure. Python has 33 unique characters that aren’t part of everyday language. Variables of many different kinds can be used in programming, such as int, float, import, if, elif, True, False, None, etc. Except for None, True, and False, all keywords in python are in must be written in lowercase. Let’s start with an analysis of a few key phrases:
- The two possible values for a Python Boolean are True and False. All of these integers are equally valid representations of the conclusion of the reasoning.
- Python allows for the use of logical operators like and, or, and not. These operations always yield a Boolean result.
- In the decision control structure, if, elif, and else are keywords; in the loop control structure, while, for, break, and continue are keywords to exit the loop or continue with the current iteration. This is the magic keyword that allows you to create your private class.
- By utilizing the def keyword, you can create a new function.
- Python’s “expect,” “try,” and “raise” keywords are used in exception handling to address a problem that arose during the execution of the program. The import keyword allows you to bring in a module from the Python standard library that isn’t already part of your current scope. The global keyword is used to access a variable declared inside a function from outside of that function.
Examples of common Python-reserved keywords are listed below. Keyword examples:
int, for, in, def, if, or, else, True, and False are all utilized in this illustration.
In this first section, we will talk about Identifiers.
Identifiers
In Python, identifiers are the names given to entities like variables, classes, and functions. There will be an immediate error in the program if we try to use keywords as identifiers. There is a standard that Python identifiers need to follow. In the following order, they are:
The only special character that is allowed is an underscore (_), hence only letters can be used in the identifier. In this case, “student name1” would be an acceptable identity.
While working with Python, several forms of capitalization have specific meanings. To give just one example, the name of the identifier and the NAME will be handled independently.
Identifying must be complete.
It is not acceptable to use “student name” as the name of a variable, for instance. It can be replaced with the format student name. The initial character of an identifier must always be a letter or an underscore. Numbers can’t be used as the initial digit in a serial number or another kind of identification. Name1, _name1, and 1name, all Python identifiers, are not permitted.
Any number of characters may be used as part of an identification.
Let’s check out some actual Python names:
Examples of valid Python IDs in their respective contexts are as follows: the “a” and “b” and “f1” and “g” lists (this is a name given to a function)
Summary
We’ve gone over the various labels and terms used in Python. We are also well-versed in Python’s syntax and the differences between keywords and identifiers as a team. Since Python is a case-sensitive language, all keywords in python are in, too. Python keywords are used for a particular purpose and have well-defined meanings. Class names, variable names, and method names are all examples of identifiers. We are unable to utilize keywords as IDs at this time. Some rules must be followed by the programmer to create names or identifiers that are considered legitimate in Python. Finally, we have finished going over Python’s keywords and identifiers.
