I have it set so if 'yea' is in the input it outputs a certain responsonce but I want it to understand yea,yes and yeah. Here is the code!
name = raw_input ("What's your name?")
if 'Sean' in name:    
name1 = raw_input("Downey or Paul?")        
if 'Downey' in name1:    
    print ("Hi Sean Downey")
    x = raw_input("Did you know that the name is irish?")
    if x == 'yea':
        print ('oh cool')
elif 'Paul' in name1:    
    print ("Hi Sean Paul")    
else:    
    print ("I don't know that Sean")
else:    
print ('Hi %s') % (name)
