3.21.1 Repr Objects
Repr instances provide several members which can be used to
provide size limits for the representations of different object types,
and methods which format specific object types.
- maxlevel
-
Depth limit on the creation of recursive representations. The
default is
6.
- maxdict
-
- maxlist
- maxtuple
- Limits on the number of entries represented for the named object
type. The default for maxdict is
4, for the others,
6.
- maxlong
-
Maximum number of characters in the representation for a long
integer. Digits are dropped from the middle. The default is
40.
- maxstring
-
Limit on the number of characters in the representation of the
string. Note that the ``normal'' representation of the string is
used as the character source: if escape sequences are needed in the
representation, these may be mangled when the representation is
shortened. The default is
30.
- maxother
-
This limit is used to control the size of object types for which no
specific formatting method is available on the Repr object.
It is applied in a similar manner as maxstring. The
default is
20.
- repr (obj)
-
The equivalent to the built-in repr() that uses the
formatting imposed by the instance.
- repr1 (obj, level)
-
Recursive implementation used by repr(). This uses the
type of obj to determine which formatting method to call,
passing it obj and level. The type-specific methods
should call repr1() to perform recursive formatting, with
level - 1 for the value of level in the recursive
call.
- repr_type (obj, level)
-
Formatting methods for specific types are implemented as methods
with a name based on the type name. In the method name, type
is replaced by
string.join(string.split(type(obj).__name__, '_').
Dispatch to these methods is handled by repr1().
Type-specific methods which need to recursively format a value
should call "self.repr1(subobj, level - 1)".
