The re.match(pattern, string) function doesn't see pattern as input?

Question

Python

I create a string s="r"regular""
I search for result=re.match(s,string) It

swears that there is a string at the input
I tried like this through compile
prog = re.compile(s)
result = prog.match(string)
But also does not search or does not see the line as it should, what am I doing wrong?
