perhaps you still relish one or two loops

open a terminal and start the interpreter

set the variable

>>> a = 0

and copy the yellow colored into the interpreter

>>> while a < 10 :
    a += 1
    print (a)

<return> 2 times



to say today you have learned and execute Fibonacci in Python
( maybe you a hacker? )

set the variables

>>> a = 0
>>> b = 1

and copy the yellow colored into the interpreter

>>> count = 0
max_count = 20
while count < max_count:
    count = count + 1
    #
    old_a = a
    old_b = b
    a = old_b
    b = old_a + old_b
    #
    #
    print (old_a),

<return> 2 times


and copy it into the interpreter once more

>>> count = 0
max_count = 20
while count < max_count:
    count = count + 1
    #
    old_a = a
    old_b = b
    a = old_b
    b = old_a + old_b
    #
    #
    print (old_a),


<return> 2 times


the variables (or values ​​to be assigned to them)
can be accessed anytime

>>> a
<return>

>>> b
<return>



a permanent background loop would thus provide constant values
