As always, use a raw string for regular expressions. \d is being interpreted
to mean an ascii character, and not to mean the character class you're trying
to reference here.
Second: \1 (if properly quoted in the string) matches the first group exactly.
Your regex would only match 20/20/2020 or strings of such format.
Third: IGNORECASE is irrelevant here, you're not trying to match letters, are
you?
Anyway, the following works:
dateregex = re.compile(r"(\d{2})/(\d{2})/(\d{4})")
m = dateregex.search(tx)
if m:
print m.groups()
else:
print "No match."
