Python Data structure exercises

1. Given the list L, such as [2,5,3,8,10,1], sort it in ascending order and output.

Code: list = [2,5,8,10,1]
Print (list)
List.sort ()
Print (list)

2. Given a string s, such as ' 123456 ', reverse it out, using slices

Code: str = ' 123456 '

Print (Str[::-1])

3. Given the dictionary dict, such as {' A ': 1, ' B ': ' 2 ', ' C ': ' 3 '}, output its key and value, respectively. Insert the dictionary {' d ': 4} into it and output the new Zid

Code:

Dict = {"A": "1", "B": "2", "C": "3"}
Print (Dict.keys ())
Print (Dict.values ())
Dict.setdefault ("D")
dict["D"] = "4"
Print (DICT)

4. Find out all primes within 100
