You can use theinoperator, thefind()method, or regular expressions to check if a string contains a substring in Python. Theinoperator returnsTrueif the substring is found, while thefind()method returns the index
12 if isinstance(v, dict): #is a instance of dict 13 stack.append((path + (k,), v)) #add key to tuple such as (xxx, yyy, zzz) and the element in stack is like ((xxx, yyy, zzz), value) 14 else: 15 result["/".join((path + (k,)))] = v 16 17 if len(current) =...
