Python random.shuffle() function to shuffle list, Option 1: Make a Copy of the Original List, Option 2: Shuffle list not in Place using random.sample(), Shuffle Two Lists At Once With Same Order, Shuffle a List to Get the Same Result Every time, Shuffle a String by Converting it to a List, Approach Two: Shuffling a String, not in place, Shuffle list not in place to return a new shuffled list. As you know, the shuffle() works in place and returns None, i.e., it changes the order of items in the original list randomly. Integral with cosine in the denominator and undefined boundaries. Appropriate changes can be made according to the platform on which the program is run. 1. .strip () .lstrip () .rstrip () Each method returns a new trimmed string. If not, it indicates that the strings contain different characters and cant be a scrambled form of each other.Below is the implementation of the above approach: Time Complexity: O(2^k + 2^(n-k)), where k and n-k are the length of the two substrings.Auxiliary Space: O(2^N), recursion stack. random.sample () returns a list even when a string or tuple is specified to the first argument, so it is necessary to convert it to a string or tuple. Here, You can get Tutorials, Exercises, and Quizzes to practice and improve your Python skills. You can initialize a random number generator with random.seed().
