this： filter(lambda x:x==None,"|",split("|"))

Re: asking
I mean any of "a","b","c" in string "adfbdfc" makes the statement true,can
I not use a function? suppose I got lots of substring let's say
s1="a",s2="b",s3="c" ...,not wrap them as a tuple or a list , just make the
statement as simple as possible to check if any of the value is the
substring of S="fasfasdfgbefve".
