MDCDict

class lsst.log.MDCDict

Bases: dict

Dictionary for MDC data.

This is internal class used for better formatting of MDC in Python logging output. It behaves like defaultdict(str) but overrides __str__ and __repr__ method to produce output better suited for logging records.

Methods Summary

clear()
copy()
fromkeys($type, iterable[, value])	Create a new dictionary with keys from iterable and values set to value.
get($self, key[, default])	Return the value for key if key is in the dictionary, else default.
items()
keys()
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised
popitem($self, /)	Remove and return a (key, value) pair as a 2-tuple.
setdefault($self, key[, default])	Insert key with a value of default if key is not in the dictionary.
update([E, ]**F)	If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
values()

Methods Documentation

clear() → None. Remove all items from D.

copy() → a shallow copy of D

fromkeys($type, iterable, value=None, /)

Create a new dictionary with keys from iterable and values set to value.

get($self, key, default=None, /)

Return the value for key if key is in the dictionary, else default.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised

popitem($self, /)

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault($self, key, default=None, /)

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None. Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values
