    – You don’t need to manage the index of the current element in the Python list. – You avoid index out-of-range error. When you find the next of the last element in the list, it returns the first element as this is a circular list. – Sometimes manipulating indexes become difficult. With cycle () and next (), you get rid of it.

    How to create list of random integers in Python?

    Complexity

  • Implementations
  • OUTPUT. Each time you will run the code you will get a different output.
  • Applications. Random number generators have applications in gambling,statistical sampling,computer simulation,cryptography,completely randomized design,and other areas where producing an unpredictable result is desirable.

    • How to search and sort lists in Python?

    You can use Python to sort a list by using sorted (). In this example, a list of integers is defined, and then sorted () is called with the numbers variable as the argument: >>> >>> numbers = [6, 9, 3, 1] >>> sorted(numbers) [1, 3, 6, 9] >>> numbers [6, 9, 3, 1] The output from this code is a new, sorted list.
