#Simple function that takes a list, finds a keyword in the 
#elements of that list and returns the elements that contain
#said keyword or not, depending upon the boolean.

myList = ['appletree','mapletree','pumpkinpie','applepie']  # Here's a list of words
keyword = 'pie' # we want to find the keyword 'pie'
isTrue = True # we want to print every element that contains the keyword 'pie'

def isinword(keyList, keyWord, isTrue): # declare our function
	if isTrue:                            # check for elements containing the keyword
		for element in keyList:
			if keyWord in element:
				print element
				
	if not isTrue:                        # check for elements without the keyword
		for element in keyList:
			if keyWord not in element:
				print element

isinword(myList, keyword, isTrue)       # call the function
