Ipython: IPython 5.0.0b2 AssertionError من داخل proc_toolkit.buffer

يبدو أن IPython سيتعطل إذا كتبت الكلمة التي تريدها بالكامل ، ولكن حاول إكمال علامة الجدولة على أي حال ثم تضغطمرة أخرى لإلغاء تحديد مربع حوار إكمال علامة التبويب.

مثال:

1. اكتب "استيراد IPython" في IPython
2. صحافةلتمكين إكمال علامة التبويب
3. صحافةمرة أخرى لإلغاء تحديد علامة التبويب إكمال
4. صحافة

إليك لقطة شاشة لوحدة التحكم تعرض خطوات النسخ المتماثل لهذا الخطأ: https://asciinema.org/a/7890yzftp8lzdjzxasrpvdnil
