Question

Use the Python programming language to complete below (I need the New Answer for this, and please provide the screenshot of the source code. Thank you!):

• 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

#python package to find patterns
import re
#inputs comma separated passwords
input_password = str(input("Enter passwords : "))
#append those passwords into a list
password_list = input_password.split(",")
#list to store valid passwords
password_valid=[]
#iterate over all the passwords in the list
for password in password_list:
    #checks all the given conditons
    if(len(password)>6 and len(password)<12):
        if(re.search("[a-z]",password)):
            if(re.search("[A-Z]",password)):
                if(re.search("[0-9]",password)):
                    if(re.search("[$#@]",password)):
                        #if all the conditons are satisfied it will be appended into list
                        password_valid.append(password)
#prints passwords comma separated
print(','.join(map(str,password_valid)))

Enter passwords : ABd1234@1,,a F1#,2w3E*,2We3345,ABd1234@2                                                                                              
ABd1234@1,ABd1234@2                                                                                                               
                                                                                                                                     
                                                                                                                                     
...Program finished with exit code 0
