Variables hold values. In Python, variables do not require forward declaration – all you need to do is provide a variable name and assign it some value.
The Python interpreter shows you a prompt that looks like this:
>>>. Each line you type into the interpreter is taken one at a time, parsed by the interpreter, and if the line is complete, executed as well.
If you enter
one = 1 in the Python interpreter and hit “Enter”, the interpreter will just show you a new line prompt.
x = 5 y = "John" print(x) print(y)
