class Bunch |
| |
Often we want to just collect a bunch of stuff together, naming each
item of the bunch; a dictionary's OK for that, but a small do- nothing
class is even handier, and prettier to use. Whenever you want to
group a few variables:
>>> point = Bunch(datum=2, squared=4, coord=12)
>>> point.datum

class RingBuffer |
| |
class that implements a not-yet-full buffer
|
| |
Methods defined here:
- __get_item__(self, i)
- __init__(self, size_max)
- append(self, x)
- append an element at the end of the buffer

class Sorter |
| |
Sort by attribute or item
Example usage:
sort = Sorter()
list = [(1, 2), (4, 8), (0, 3)]
dict = [{'a': 3, 'b': 4}, {'a': 5, 'b': 2}, {'a': 0, 'b': 0},
{'a': 9, 'b': 9}]
sort(list) # default sort
sort(list, 1) # sort by index 1
sort(dict, 'a') # sort a list of dicts by key 'a'

- __call__ = byItem(self, data, itemindex=None, inplace=1)
- byAttribute(self, data, attributename, inplace=1)

class Xlator(__builtin__.dict) |
| |
All-in-one multiple-string-substitution class
Example usage:
text = "Larry Wall is the creator of Perl"
adict = {
"Larry Wall" : "Guido van Rossum",
"creator" : "Benevolent Dictator for Life",
"Perl" : "Python",
}
print multiple_replace(adict, text)
xlat = Xlator(adict)
print xlat.xlat(text)

- D.copy() -> a shallow copy of D
- get(...)
- D.get(k[,d]) -> D[k] if k in D, else d. d defaults to None.
- has_key(...)
- D.has_key(k) -> True if D has a key k, else False
