1. Sharing helps me continue to create free Python resources. The python string decode () method decodes the string using the codec registered for its encoding. Make a copy of the original list before shuffling (Ideal and preferred), Use the random.sample() function to shuffle list not in place to get the new shuffled list in return instead of changing the original list. You can read the full documentation here. Find centralized, trusted content and collaborate around the technologies you use most. For example, the scramble ("12") should compute the scramble of "1", which is "1", interleaved with the scramble of "2", which is "2". Suppose, we choose the node co and swap its two children, it produces a scrambled string ocder. Create a map of characters and integers. Basically, what it does is just take in a string, convert it to a list, and make a temporary copy. Does Python have a string 'contains' substring method?
