What are the rules for variables in Python language?
The rules for variables in Python language are:
1. Variable name can start with a letter or underscore ( _ ) character only which means it cannot start with a number.
2. Python is a case-sensitive language which means variable names are also case-sensitive.
Example - These three are different variables gender, GENDER, Gender
3. Variable names can only have alphanumeric characters (A-Z, a-z, and 0-9) and underscore ( _ )
Variable can be short or long/descriptive.
Example - x, y, z, age, gender, Address, _var, etc.
What is case sensitivity?
Case sensitivity is the term that tells us about the programming language capability of making out differences between Upper Case Letters and Lower Case Letters.
"2. Unlimited length"
Explanation:
A variable can have a short name (like x and y) or a more distinct name (age, carname, total_volume).
Rules for Python factors:
A variable name should begin with a letter or the highlight character
A variable name can't begin with a number
A variable name can just hold back alpha-numeric characters and highlights (A-z, 0-9, and _ )
Variable names are case-delicate (age, Age and AGE are three distinct factors)
