[issue46574] itertools.count should work with non-number types
New submission from Mital Ashok :
There's no reason that `count('', 'a')` for `'', 'a', 'aa', ...` or `count((),
(1,))` for `(), (1,), (1, 1), ...` shouldn't work.
count(a, b) should be equivalent to accumulate(chain((a,), repeat(b)))
The docs don't strongly suggest that it won't work (it says *start* is a
number, but the "roughly equivalent to" generator would work for str/tuple/etc)

[issue31504] Documentation for return value for string.rindex is missing when search string is empty
Ashok Bakthavathsalam added the comment: The documentation (https://docs.python.org/3/library/stdtypes.html#str.find) does not describe what will be the behaviour if the substring is "". And by the way, as per https://docs.python.org/3/reference/expressions.html#membership-test-operations, Empty strings are always considered to be a substring of any other string, so "" in "abc" will return True. Returning an invalid index value, although confusing, should at least be documented in some form. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31504> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

string.find() also exhibits the same behaviour.
"abcde".find("") -> 5 which also is not documented anywhere.

[issue30955] \\N in f-string causes next { to be literal if not escaped
New submission from Mital Ashok:
Take this format python code:
import unicodedata
c = chr(0x012345)
To print that character as a string literal, you would expect to do:
print(f"'\\N{{{unicodedata.name(c)}}}'")
Which should print a literal quote (`'`), a backwards slash (`\\` -> `\`), an
`N`, and the two `{{` should escape and print `{`, followed by the f-expression
`unicodedata.name(c)`, then the `}}` would print one `}`, and then another
literal quote (`'`).
However, this raises a `SyntaxError: f-string: single '}' is not allowed`. The
way to do this without a syntax error is like so:
print(f"'\\N{{unicodedata.name(c)}}}'")
Which prints the expected:
'\N{CUNEIFORM SIGN URU TIMES KI}'
The shortest way to reproduce this is:
f'\\N{'
Which works, and:
f'\\N{{'
which raises an error, even though the first one should raise an error
(`SyntaxError: f-string: expecting '}'`).

However I m not able to get the exact match. Could someone help? print a c c+ b 'c+' re.search(b,a).group() 'c' In the above example I want re to find the string 'c+' instead of 'c'.

Repost: Read a running process output
Hi,
I very badly need this to work. I have been googling out for a week
with no significant solution. I open a process p1 which does keeps
running for 4+ hours. It gives some output in stdout now and then. I
open this process with subprocess.Popen and redirect the stdout to
PIPE. However when I read the output with readline it blocks waiting
forever. I need to read from p1.stdout till what it has in the PIPE.
Can someone help me out with the exact code change that can accomplish
the task.
from subprocess import *
p1=Popen('/usr/sunvts/bin/64/vtsk -d',stdout=PIPE,shell=True)
while 1:
line=p1.stdout.readline()
print line

You forgot to change the monolithic command into a list of words. Since
you don't use the shell anymore you have to give Popen a pre-parsed

I m trying a read the output of a process which is running

I tried a lot of methods but to no avail. It would be great if someone
can make it work.
