Inline::Python inspects the main namespace of the Python code and imports those names into the current package. Thus you have to specify the fully qualified name of the imported class: package TestPy; use Inline Python => 'from StringIO import StringIO'; my $stringio = TestPy::StringIO->new; It's the same as when your TestPy package imports names from other Perl modules. Your test script worked because in Perl you don't have to qualify names in the main package, though doing so works as well: package main; use Inline Python => 'from StringIO import StringIO'; my $stringio = main::StringIO->new; # works my $stringio = ::StringIO->new; # shortcut works, too my $stringio = StringIO->new; # unqualified works as well Regards, Stefan
