Parameters
----------
value : str
The string to be converted. This can be either a single number, a
range expression in the form of min:max or min:step:max, or even a
list containing numbers and range expressions.
min : int
The minimum allowed value. If the converted value is (or have)
lower than `min` then the VdtValueTooSmallError exception will be
raised.
max : int
The maximum allowed value. If the converted value is (or have)
greater than `man` then the VdtValueTooSmallError exception will be
raised.
Returns
-------

Notes
-----
You can either separate the values with commas or spaces (any comma
will have the same effect as a space). However, if you separate with
spaces the values should be brackets, while if you separate with
