Python Variable Name Rules
What are Variable Name Rules in Python?
Python is not a "statically typed" programming language. We don't need to define variables or their types before utilizing them. When initially a value is assigned to a variable, it is said to be created.
A memory region is given a name called a variable. It is a program's fundamental storage unit.
The following are the rules for defining variables in Python:
A variable's name must begin with a letter or a single underscore.
The initial character in a variable name cannot be a number.
In variable names, only alpha-numeric characters and underscores (A-z, 0-9, and _) are permitted.
When it comes to variable names, the character case matters (name, Name, and NAME are three different variables).
The use of reserved terminology (keywords) in the variable's name is prohibited.
1x wrong variable
#name wrong variable
__x wrong variable
.x wrong variable
X. wrong variable
X1 right variable
X_ right variable
_x right variable
