if you want to print "|\|", why are you printing the list?

there's only one in the string; the other one is added by the list-
to-string conversion. if you print the *list item* instead, only one
backslash is printed.
the correct way to add a single backslash to a string is to write *two*
backslashes in the string literal, like this:
"|\\|"
this results in a 3-character string, which is printed as |\|, but is
echoed back as '|\\|' by the repr() operator (which is used by the
interactive prompt, and the list-to-string conversion, among others).
>>> s = "|\\|"
>>> s # implicit repr
'|\\|'
>>> print s
|\|
>>> len(s)
3
>>> print repr(s)
'|\\|'
>>> print str(s)
|\|
>>> x = [s]
>>> x # implicit repr
['|\\|']
>>> print x[0]
|\|
</F>
