duplicate = 0 for i in range(len(stack)-1,0,-1): if stack[i] == stack[i-1]: duplicate += 1 else: break else: stack.append(letter) else: stack.append(letter) duplicate = 0 return "".join(stack) 1. 2. 3. 4. 5.
Since the keys in a dictionary are unique, the duplicate values are dropped when creating the dictionary. The keys are guaranteed to have the same order as the items in the list if using Python 3.7 or later. All keys have a value ofNoneby default. However, the values aren't required si...
