About Python Re Raw Pattern Search

I want to perform re.search using the pattern as a raw string like below. m=re.search(r'pattern',string) But if I have the 'pattern' in variable like pat='pattern'. How do I perfo

Solution 1:

You declare the pattern string as a raw string:

regexpattern = r'pattern'
m=re.search(regexpattern,string)

Solution 2:

you can give the raw input this way. test is the string variable.

pat = """pat%s""" % test

pattern = re.compile(pat, re.I | re.M)

match = pattern.search(l)
