For domain in domains:
prefix = getprefix (domain)
Postfix = getpostfix (domain)
Domainlen = len (prefix)
if (Domainlen < min) or (Domainlen > Max):
Len_num +=1
Continue
If Hasmidline (prefix):
Mid_line_num +=1
Continue
Result.append (Domain)

print "log: \ n"
print "All: \ T", Len (Domains)
Print "Len not in [%s,%s] \ t:%s"% (Max,min,len_num)
Print "Contain '-': \ T", mid_line_num

url = getUrl ()
Source = GetSource (URL)
Save (source)

result = Parser (domains)
Save ("". Join (Result), "Result.txt")
Print ("\n\n\nfinished!!")


Output file:
domains.txt:kingnic.com the domain name that was released on that day;
Result.txt: The domain name that conforms to the filter condition;
Log output:
