Why doesn't it not working properly???

Question

b = {'9':'0','8':'1','7':'2','6':'3','5':'4','4':'5','3':'6','2':'7','1':'8','0':'9'}
y = input()

for key, value in b.items():
y = y.replace(key, value)

Answer 5

Shahir How about this one? :-

b = {ord(x):ord(y) for x, y in b.items()}
print(input().translate(b))

Or this one? :-

print("".join(b.get(x, x) for x in input()))

# Hope this helps
