Python Variables:
What is Variable in Python Programming Language?
✅Variable is used to store data.
✅Variable act as containers to store values (data).
✅The values can be anything, like integer(numbers), float (decimal point numbers), string (letters, words, sentences).
✅A variable in python can be referred to using Variable names.
🔵For eg:
Library,
in the library, there are many sections that are labeled.
so if I want to put an English book, I will keep it in the section labeled as English.
In this example,
✅in that inside library bookshelf, it can be used to store the books.
✅Similarly, in programming, Variable act as containers to store values.
✅And just like the labels of a bookshelf,
☑️A bookshelf is a container (Variable)
☑️A label is a Variable name
example:
✅The box is a Variable, the box name is a variable name and inside that values.
🔴 3 things are required to store value in #Variable
1. Variable name
2. Assignment Operator (equal to) =
3. Value
✅For example:
name = Deepak
✅name is a variable name
✅= is an assignment operator
✅Deepak is a value, stored in the name (variable).
-we can also store text in variables.
🟠Text values are known as a string in a programming language.
✅Anything written between double quotes “ “ or single quote is a string in #python.
✅”Deepak” is a string and the “123” number inside quotes is also considered as a string in python.
✅Decimal point numbers are known as a floating-point number in programming.
✅A floating-point number refers to a number consisting of two parts separated by a decimal point.
✅A whole number is known as an integer in programming.
🟢 number=3 # an integer, 3 is an integer.
🟢 num=3.3 # an floating-point number.
🟠 If we want to find what type of value we had store then
✅ type(variable_name),
variable name inside the curved bracket.
