What Is Variable in Python

In programming, a variable is a named location in memory where you can store a value. In Python, you can use variables to store data, such as numbers, strings, and lists.

Here's how you can create a variable in Python:

# assign an integer value to a variable
x = 10
 
# assign a string value to a variable
name = "John Doe"
 
# assign a list value to a variable
fruits = ["apple", "banana", "cherry"]

In the examples above, x, name, and fruits are the names of the variables, and the values to the right of the equal sign are the values that are being stored in those variables.

You can use the variables in your code just like you would use the values themselves:

 
# print the value of the variable x
print(x) # 10
 
# print the value of the variable name
print(name) # John Doe
 
# print the value of the third item in the list stored in the variable fruits
print(fruits[2]) # cherry

Note that in Python, the type of a variable is determined automatically based on the value assigned to it. For example, the type of the x variable is an integer, the type of the name variable is a string, and the type of the fruits variable is a list.

It's important to choose descriptive and meaningful names for your variables, as this will make your code easier to read and understand.
