If you want to use the reprlib.Repr class, currently, you need to instantiate an object and then set the desired attributes, afterwards, before you can actually use it:

from reprlib import Repr
myrepr = Repr()
myrepr.maxlevel = 10
myrepr.maxlist = 3
myrepr.maxdict = 1
myrepr.repr(myobject)

It might be more comfortable and clearer sometimes, to be able to set the attributes during the initialization:

from reprlib import Repr
myrepr = Repr(maxlevel=10, maxlist=3, maxdict=1)
myrepr.repr(myobject)

Furthermore, this would make it possible to use reprlib.Repr without having to designate a permanent name:

from reprlib import Repr
Repr(maxlevel=10, maxlist=3, maxdict=1).repr(myobject)
