"Templating" (copying an input file to output, on the fly inserting Python expressions and statements) is a frequent need, and YAPTU is a small but complete Python module for that; expressions and statements are identified by arbitrary user-chosen regular-rexpressions.



Python does not automatically call the __init__ (and __del__) methods of superclasses if subclasses define their own; explicit calling is needed, and it may be advisable to use a call-if-it-exists idiom.



In Python, any variable can be re-bound at will -- and modules don't let you define special methods such as an instance's __setattr__ to stop attribute re-binding. Easy solution (in Python 2.1 and up): use an instance as "module"...



You want to convert tabs in a string to the appropriate number of spaces, or vice versa.



Special method __copy__ is the easiest way for an object to cooperate with the copy.copy function, but how do you bypass the object's __init__, if it's slow, to get an 'empty' object of this class? Easy -- here's how.



Python has no equivalent to Java's "super" keyword (so that some part of a method can be delegated to the superclass), but it's easy to get similar convenience despite Python's multiple-inheritance generality.



Python's "in" operator is extremely handy, but O(N) when applied to an N-item sequence; if a sequence is subject to frequent "in" tests, an auxiliary dictionary at its side can boost performance A LOT if the values are hashable.



You want to reverse the characters or words of a string.



Python's "if" is a _statement_, and there is no conditional _operator_ (like C's "a?b:c" ternary) that we could use where expressions are needed (lambdas, etc); however, with some due care, equivalents can easily be coded.



Python lists' .sort method is not guaranteed stable -- items that compare equal may or may not be in unchanged order. Ensuring stability is easy as one of the many application of the commom idiom decorate-sort-undecorate (aka "Schwartzian...
