Jestem w stanie poprawnie to odczytać w Perlu przy użyciu YAML, ale nie w Pythonie za pomocą YAML. Błąd z powodu błędu:

oczekiwał pojedynczego dokumentu w strumieniu

Program:

import yaml

stram = open("test", "r")
print yaml.load(stram)

Błąd:

Traceback (most recent call last):
  File "abcd", line 4, in <module>
    print yaml.load(stram)
  File "/usr/local/pkgs/python-2.6.5/lib/python2.6/site-packages/yaml/__init__.py", line 58, in load
