What is Python variable?
A Variables play a very important role in other Programming languages, and Python is no exception. A Variable allows you to store values by assigning it to a name, which can be used to refer to the value later in the program
Creating Variables
Unlike other programming languages, Python has no command for declaring
A variable is created the moment you first assign a value to it.
Example:
>>> x=3 # x is the type of Int
>>> print(x)
3
>>> print(x+3)
6
>>> print(x)
3The variable can be reassigned as many times as you want, in order to change their value.
In python, the variables don’t have specific types, so you can assign a string to
Example:
>>>x=45.23 # x is the type of Int
>>> print(x)
45.23
>>> x="this is string" # x is the type of String
>>> print (x)
this is string
>>>print(x + "!")
this is string!- To combine both text and a variable, Python uses the
+character:
Example:
>>> x = "awesome"
>>> print("Python is " + x)
Python is awesome
