Hi,
I use the following code to process TSV input.
$ printf '%s\t%s\n' {1..10} | ./main.py
['1', '2']
['3', '4']
['5', '6']
['7', '8']
['9', '10']
$ cat main.py
#!/usr/bin/env python
# vim: set noexpandtab tabstop=2 shiftwidth=2 softtabstop=-1 fileencoding=utf-8:
import sys
for line in sys.stdin

Hi,
I recently discovered the wonders of pip.conf: if I create a file
~/.config/pip/pip.conf* with:
[install]
user = true
then pip will install to the --user site-packages by default, rather
than trying to install packages into system directories.

It errors out:

Can not perform a '--user' install. User site-packages are not visible

Hmm setting the timeout might not be the solution. This is from the docs

Or maybe I misunderstood the docs and the timeout means the max. time
elapsed between receiving two chunks of data from the server?

a bad idea.

another thing which amazed me with pip is that you can write
library1 == 1.2.7
library2 == 3.6.1
in requirements.txt
and pip install requirements.txt will install those libs
