[Zope] FindOneOf?

ColdFusion (I know, a dirty word ;-) ) has a nifty string function called "FindOneOf" which returns the index of the occurrence of any character in a string. Example: FindOneOf("ghd", "abcdefghij", 1) Will return a "4" because "d" is the fourth letter in the string "abcdefghij". If no match is made, a 0 is returned. This is especially useful when building a change password form, because I can easily check to see that the new password contains at least one special character, upper case character, number, etc. Is there anything similar to FindOneOf in ZOPE? If not, does anyone have any hints on how I can go about doing this kind of thing through dtml or python? -=Brad=-
