function to count down then up on button press

(OP)
Hello, first I want to start off by saying I'm super new to coding and learning and my project is in Micropython which I guess is a version of python. My question is I have a beginner project I been wanting to do and its almost done except I needed to add a counter for a button. This counter is for each button press, I need the counter to start off with each press 4,3,2,1,0 then 1,2,3,4,5,6 and so on adding 1 with each press. What I have now is with each press it counts like;

-1, -2, -3, -4, -5, 6, 7, 8, 9........

Please help I been at this for days.. Thanks!

CODE --> micropython

import utime
import machine

B1 = machine.Pin(14, machine.Pin.IN, machine.Pin.PULL_DOWN)  #C to 3.3v, NO to GPIO 14

B1_clicks = 0

def round_counter():
    global B1_clicks
    if B1.value():  #Was the B1 button pushed?
        B1_clicks += 1
    if B1_clicks > 4:
        print('Rnds: {}'.format(B1_clicks))  
        utime.sleep(0.25)  #Pause
    else:
        print('Rnds: -{}'.format(B1_clicks))
        utime.sleep(0.25)  #Pause

Your written requirements and your code are substantially divergent.

@mintjulep please talk hillbilly cuz I have no idea what your talking about....Im to the point Im done with trying to figure this out...

RE: function to count down then up on button press

Not sure I am fully understanding your question

if you want a circular counter the use modulo arithmatic

a=0
while True:
a = (a+1) % 6
print(a)

will get you a couht that cyles 0-5
if you want +V & negative numbers arround 0 then add & subtract an offest a= ((3+ a + 1) %6) -3

hope this at leasts helps you towards your solution

Do things on the cheap & it will cost you dear
