def main():

def countPoints(rings: str) -> int:

counter=0

for rod in range(0,1):

list=[]

for index, digit in enumerate(rings):

if(digit == rod):

list.append(rings[index-1])

if ("R") in list and ("G") in list and ("B") in list:

counter+=1

return counter

print(countPoints("B0B6G0R6R0R6G9"))

if __name__ == "__main__":

main()

QUESTION: Why does the statement if(digit==rod) return false even when digit is 0?
