if_pairs_of_nonnegative_ints(obj, obj_name)[source]

Check whether input object is a sequence of pairs of nonnegative integers.

If the input object is not a sequence of pairs of nonnegative integers, then an exception is raised with the message:

The object ``<obj_name>`` must be a sequence of pairs of nonnegative
integers.

where <obj_name> is replaced by the contents of the string obj_name. In the case that an exception is raised, said exception is of the type TypeError if the input object is not a sequence of pairs of integers, otherwise said exception is of the type ValueError.

Parameters:

objany type: Input object.
obj_namestr: Name of the input object.
