Hi,
While working on some python C extensions, I got curious in how things
work for printing float objects (and C-level objects which inherit
from it). In python 2.6, I understand that the formatting went into
surgery for more consistency across platforms. So for example, on
windows, complex('inf') would be printed 'inf', and not '1.#INF'.
However, I would like some clarifications if possible about the
following:
a = complex('inf')
print a # -> print 'inf'
print '%s' % a # -> print 'inf'
print '%f' % a # -> print '1.#INF'
My understanding is that in the first case, the formatting is
controlled through the tp_print and in the second case, from str(a)
behavior (tp_str). Can the 3rd one be controled at all ? Or is it
going directly through the underlying C runtime, without python doing
any formatting (which is how I understand the inconsistency). Is this
by design ?
thanks,
David
