Maybe I have something else wrong too? complete_text = Tbox.get("1.0", END) greenList = "green grass".split() greenList_regexp = "|".join(greenList) for matchobj in re.finditer(r'\b(?:' + greenList_regexp + ')\b', complete_text): start,end = matchobj.span() Tbox.tag_add("green", "1.0 + %d chars" % start,"1.0 + %d chars" % end) Tbox.tag_config("green", foreground="green") The words "green" and "grass" do not turn green.
