Variables in Python [Explained]
Create variables in python
- There is no command or specific syntax for variables in python.
- Variables are created when you assign a value to it:
a = 5 b= 2 c = "Hello, World!" print(a) print(b) print(c)
- You don’t need to specify the type of the variable before assigning it.
- In the example above ‘a’ variable is an integer and ‘c’ is a string and both are assigned in the same way.
