Comparable values

For certain types you can't make comparisons out of the box in Python but Validation brings support to a few of them.

You can make comparison with the following data types:

  • Countable: any object that has attribute __len__
  • datetime objects
  • String which can be converted to datetime based on ISO format
  • Integer types (int, float, bool)
  • Single character string
  • If string is digit, then it will be treated as integer
  • String with more than one character comparable by length

Below you can see some examples:

#  int compare with range
v.Min(100).validate(range(101))  # true if it has at least 100 items

#  datetime support
yesterday = datetime.today() - timedelta(days=1)
tomorrow = datetime.today() + timedelta(days=1)
now = datetime.today()

v.dateTime()\
    .between(yesterday, tomorrow)\
    .validate(now)  # true

#  int compatible with str
v.digit().Max(10).validate('5')  # true

v.stringVal().between('a', 'f').validate('d')  # true

v.dateTime().between('2022-04-01', '2022-04-15').validate('2022-04-07 10:12:11')  # true
