Please guide me how to install Haskell on

问题 Is there an elegant and more Python-like way to check if a package is installed on Debian? In a bash script, I'd do: dpkg -s packagename | grep Status Suggestions to do the same in a Python script? 回答1: This is a pythonic way: import apt cache = apt.Cache() if cache['package-name'].is_installed: print "YES it's installed" else: print "NO it's NOT installed" 回答2: If you are checking for the existence of a package that installs a Python module, you can test for this from within a dependent
