The Library Reference says this about built-in repr():
Return a string containing a printable representation of an object.
While studying Programming Python, 2nd Ed. Example 2-18, p. 84, I was
wondering what the point was of applying repr to a component (dir) of
sys.path. Isn't it after all, already a printable string? Ok, so
what does it mean to take repr of a printable string, and why does
the author want to here? Are we worried that the path contains an
unprintable directory name or something?
I tried this:
>>> str = 'dog'
We now seem to have a string with quote characters as its first
and last components. I would have thought that the operation of
making a printable representation of something that is already
printable would be the identify function. Could someone
explain precisely what is going on here?
