Find which, if any, dictionary values exist in a string in Python? -

so i'm finding ways find if key/value exists in string, i'm not finding examples allow me access key/value found in string.

basically, have string. let's say:

body = "hi name john" 

...and have following dictionary:

names = {"john": "john", "bill": "bill", "jordan": "jordan"} 

i want see if of names in dictionary contained in string, , if so, want know 1 (assign variable or whatnot).

if assume have these mapped in dictionary reason, i'll show yes it's possible utilize mappings in ways this:

    class bodytests():         def __init__(self):             self.namemap = {"john": "johnathon", "johnathon": "johnathon", "bill": "william", "wil": "william"}             self.greetmap = {"hi": "hello", "aloha": "hello", "hello": "hello", "salutations": "greetings"}          def find(self, lookfor, searchin):             return set(lookfor.get(x) x in lookfor.viewkeys() & searchin.split())          def findguys(self, abody):             return self.find(self.namemap, abody)          def findgreets(self, abody):             return self.find(self.greetmap, abody)       body = "hi name john\nplease call me john\ni wish named bill"     foundnames = bodytests().findguys(body)     foundgreets = bodytests().findgreets(body)     print "python set of names: ", foundnames     print "python set of greets: ", foundgreets     print "let's dump them out: "     s in foundnames:         print s     s in foundgreets:         print s     exit() 

python set of names: set(['william', 'johnathon'])
python set of greets: set(['hello'])
let's dump them out:
william
johnathon
hello
