Question

USE PYTHON :

# Problem Set 04:
- Write a function to seek for all even numbers and odd numbers in the middle of two number A and B. Print even and odd numbers in 1 and 2020 (including both these two numbers)

# Problem Set 05:
- A website requests an user to input his account password.
- Write a program to examize the validity of the password.
- The valid password must consists of:
- At least 1 letter in [a-z]
- At least 1 number in [0-9]
- At least a letter in [A-Z] (capital)
- At least one special letter in [$#@]
- At least 6 letters in total
- At most 12 letters in total
- The program can accept a list of passwords that are split by commas.
- Print all valid passwords in a line and split by commas
- Examples:
- Input: ABd1234@1,a F1#,2w3E*,2We3345
- Output: ABd1234@1
