5.19.1 Repr Objects
Repr instances provide several members which can be used toprovide 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
- maxset
- maxfrozenset
- maxdeque
- maxarray
- Limits on the number of entries represented for the named object type. The default is
4 formaxdict,5 formaxarray, and6 for the others.New in version 2.4:maxset,maxfrozenset, andset..
- 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 theRepr object. It is applied in a similar manner asmaxstring. The default is
20.
- The equivalent to the built-inrepr() that uses the formatting imposed by the instance.
- Recursive implementation used byrepr(). This uses the type ofobj to determine which formatting method to call, passing itobj andlevel. The type-specific methods should callrepr1() to perform recursive formatting, with
level - 1 for the value oflevel in the recursive call.
- 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 byrepr1(). Type-specific methods which need to recursively format a value should call "self.repr1(subobj,level - 1)".
Release 2.5.2, documentation updated on 21st February, 2008.
