पायथन इंटरप्रिटर में, 08 और 09 अमान्य लगता है उदाहरण: 

  & gt; & gt; & gt; 01 1> gt; & gt; 02 2> gt; & gt; & gt; 03 3> gt; & gt; & gt; 04 4 & gt; & gt; & gt; 05 5> gt; & gt; & gt; 06 6 & gt; & gt; & gt; 07 7> gt; & gt; 08 फ़ाइल "& lt; stdin & gt;", पंक्ति 1 08 ↑ सिंटेक्स एरर: अमान्य टोकन & gt; & gt; & gt; 09 फ़ाइल "& lt; stdin & gt;", रेखा 1 9 ^ सिंटेक्स एरर: अमान्य टोकन

जैसा कि आप देख सकते हैं, केवल 08 और 09 काम करने के लिए प्रतीत नहीं होता क्या इन विशेष मूल्यों या कुछ चीजें हैं?

एक अग्रणी शून्य के साथ एक संख्या ओक्टल शब्दशः के रूप में व्याख्या की जाती है। तो 8 और 9 अक्तूबर में अमान्य हैं I केवल 0 से 7 अंक मान्य हैं।

इंटरप्रेटर में प्रयास करें: 

  & gt; & gt; & gt; 011 9 & gt; & gt; & gt; 012 10 & gt; & gt; & gt; 013 11
