The string object in python does not have the contains method. You do not need to use the string. contains method to determine whether a sub-string is contained. However, python has a simpler method to replace the contains function.

Method 1: Use the in method to implement the contains function:

Site = 'HTTP: // www.bkjia.com/'if "jb51" in site: print ('site contains jb51 ')

S = "This be a string" if s. find ("is") =-1: print "No 'is' here! "Else: print" Found 'is' in the string ."
