Rules for Declaring Variables in Python
There are a few rules that you need to follow when declaring variables in Python:
Variable names can only contain letters, numbers, and underscores. They cannot contain spaces or special characters. Variable names cannot begin with a number. Variable names are case-sensitive, so name and Name are considered to be two different variables. Python has a number of reserved words that cannot be used as variable names. These include keywords such as for, while, and def.
Naming Conventions for Variables in Python
There are a few naming conventions that are commonly followed when declaring variables in Python:
Variable names should be descriptive and meaningful. For example, it’s better to use first_name instead of fn. Variable names should be in lowercase, and words should be separated by underscores. For example, first_name is a better variable name than firstName. Constants, which are variables that are meant to be unchanging, should be in uppercase and words should be separated by underscores. For example, PI is a good name for a constant that represents the value of Pi.
Declaring Variables in Python
Declaring a variable in Python is simple. All you need to do is give the variable a name and assign it a value using the “=” operator. For example:
In this example, we are declaring two variables: name, which is a string, and age, which is an integer.
It’s important to note that in Python, you don’t need to specify the type of a variable when you declare it. The type of a variable is determined by the value you assign to it. For example, if you assign a string value to a variable, it will be treated as a string, and if you assign an integer value to a variable, it will be treated as an integer.
You can use the type() function to determine the type of a variable in Python. For example:
