class
shamo.core.problems.single.abc.
ProbABC
[source]¶ -
A base class for any problem.
All the main processes are defined as problem/solution pairs. The problem defines the parameters and builds the solution.
Methods
Create a new dictionary with keys from iterable and values set to value.
Return the value for key if key is in the dictionary, else default.
If key is not found, d is returned if given, otherwise KeyError is raised
Remove and return a (key, value) pair as a 2-tuple.
Insert key with a value of default if key is not in the dictionary.
Solve the problem and build the solution object.
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]
-
clear
() → None. Remove all items from D.¶
-
copy
() → a shallow copy of D¶
-
fromkeys
(iterable, value=None, /)¶ Create a new dictionary with keys from iterable and values set to value.
-
get
(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
(/)¶ 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
(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.
-
abstract
solve
(name, parent_path, **kwargs)[source]¶ Solve the problem and build the solution object.
- Parameters
- name
str
The name of the solution.
- parent_path
str
,byte
oros.PathLike
The path to the parent directory of the solution.
- name
- Returns
shamo.core.objects.ObjDir
The solution.
-
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¶
