python - Maximum time to wait for url response -


i'm making simple update checker function code set run every time before bulk of code executed. notifies user new version available download.

here's mwe:

import urllib  def updater(__version__):     try:         # latest version number master repo @ github.         f = urllib.urlopen("https://raw.githubusercontent.com/chrisglass"             "/django_polymorphic/master/polymorphic/__version__.py")         s = f.read().split('"')          if s[-2] != __version__:             print "new version {} available.".format(s[-2])     except:         pass  # call function check if new version available. __version__ = '0.1' updater(__version__)

(that repo isn't mine, i'm using in example because use similar version of __version.py__ file)

this works fine, i'm concerned github taking long respond, hold execution of code.

is there way jump out of try block after 5 seconds have elapsed? recommended way go this?

use urllib2, urlopen has timeout parameter.

urllib2.urlopen(url[, data[, timeout[, cafile[, capath[, cadefault[, context]]]]])

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
