We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.

Here is the Python code.

import re

wordText1 = "We hold these truths to be self-evident, that all men are created equal"

def toWordSet1(text1):
	text1 = text1.lower()
	wordList1 = re.findall("[a-z']+",text1)
	wordSet1 = set(wordList1)
	return wordSet1

wordSet1 = toWordSet1(wordText1)
wordText2 = " ".join(wordSet1)
print("Text: {0:s}".format(wordText1))
print("Words: {0:s}".format(wordText2))
print("Words:")
for word1 in wordSet1:
	print("\t{0:s}".format(word1))
	#end for

Here is the output of the Python code.

Text: We hold these truths to be self-evident, that all men are created equal
Words: hold all equal created be men self these we that truths are to evident
Words:
	hold
	all
	equal
	created

	men
	self

Here is the Python code.

import re

wordText1 = "We hold these truths to be self-evident, that all men are created equal"

wordList1 = []

def wordFix1(match1):
	word1 = match1.group(1)
	wordList1.append(word1)
	return "."


def toWordSet1(text1):
	global wordList1
	wordList1 = []
	text1 = text1.lower()
	text2 = re.sub("([a-z']+)",lambda x: wordFix1(x),text1)
	print("Text:")
	print("\t{0:s}".format(text1))
	print("Replaced text:")
	print("\t{0:s}".format(text2))
	wordSet1 = set(wordList1)
	return wordSet1


wordSet1 = toWordSet1(wordText1)
wordText1 = " ".join(wordSet1)
print("Words: {0:s}".format(wordText1))

Here is the output of the Python code.
