3.24.1 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.
Depth limit on the creation of recursive representations. The
default is 6.
- Limits on the number of entries represented for the named object
type. The default for maxdict is 4, for the others,
Maximum number of characters in the representation for a long
integer. Digits are dropped from the middle. The default is
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.
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
- 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
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)".
