Description:
 def multenterbox(msg="Fill in values for the fields.", title=" ", fields=(), values=()):
 r""" Show screen with multiple data entry fields. If there are fewer values than names, the list of values is padded with empty strings until the number of values is the same as the number of names. If there are more values than names, the list of values is truncated so that there are as many values as names. Returns a list of the values of the fields, or None if the user cancels the operation. Here is some example code, that shows how values returned from multenterbox can be checked for validity before they are accepted:: msg = "Enter your personal information" title = "Credit Card Application" fieldNames = ["Name","Street Address","City","State","ZipCode"] fieldValues = [] # we start with blanks for the values fieldValues = multenterbox(msg,title, fieldNames) # make sure that none of the fields was left blank while 1: if fieldValues is None: break errmsg = "" for i in range(len(fieldNames)):
 if fieldValues[i].strip() == "": errmsg += ('"%s" is a required field.\n\n' % fieldNames[i]) if errmsg == "": break # no problems found fieldValues = multenterbox(errmsg, title, fieldNames, fieldValues) print("Reply was: %s" % str(fieldValues)) :param str msg: the msg to be displayed. :param str title: the window title :param list fields: a list of fieldnames. :param list values: a list of field values :return: String """
