python: regex match string and only string [duplicate]

I'm trying to create a small, text restriction program in python. Basically, the user inputs the text, some filters (a for alphabetic, n for numeric, etc.). The user can combine filters (a and n for alpha-numeric, etc.) but I stumbled upon this:

if re.match("[a-zA-Z]", textToRestrict):
    return True
else:
    return False

Here's where things fall apart. Supposedly, with only alphabetic as a filter, the program will only accept strings, such as, say, dance. However, the if statement still returns true if the textToRestric was, say, dance1234 (incorrect) while 1234dance will return false (correct).

Conversely, if I test for digits via [0-9], it would still return true even if it contains alphabetic characters, provided that the characters aren't the first.

How do I use regex to match only a certain type, and in such a way that adding another type to it (like type string + type digit) allows for both types return true?

UPDATE: This is the approach I used for multiple filters:

regex = ""
if FilterClass.ALPHABETIC in arguments:
    regex += "[a-zA-Z]"
if FilterClass.CAPITAL_ALPHABETIC in arguments:
    regex += "[A-Z]"
if FilterClass.NUMERIC in arguments:
    regex += "\d"
if FilterClass.SPECIAL_CHARACTERS in arguments:
    regex += "[^0-9a-zA-Z]*"
if FilterClass.DASH_UNDERSCORES in arguments:
    regex += "[-_]*"            

regall = "^(" + regex + ")+$"

if re.match(regall, textToRestrict):
    return True
else:
    return False

arguments is a parameter inputted in by the user. The if statements check what's in there, and, supposedly, add more patterns to the regex string.
