Update of /cvsroot/python/python/dist/src/Lib
In directory usw-pr-cvs1:/tmp/cvs-serv7871/python/Lib
Modified Files:
pstats.py
Log Message:
Widespread random code cleanup.
Most of this code was old enough to vote. Examples of cleanups:
+ Backslashes were used for line continuation even inside unclosed
bracket structures, from back in the days that was still needed.
+ There was no use of % formats, and e.g. the old fpformat module was
still used to format floats "by hand" in conjunction with rjust().
+ There was even use of a do-nothing .ignore() method to tack on to the
end of a chain of method calls, else way back when Python would print
the non-None result (as it does now in an interactive session -- it
*used* to do that in batch mode too).
+ Perhaps controversial (although I can't imagine why for real <wink>),
used augmented assignment where helpful. Stuff like
self.total_calls = self.total_calls + other.total_calls
is just plain harder to follow than
self.total_calls += other.total_calls
