Is there something wrong with the Python Shell (Google app)?

Python Shell - shell.appspot.com acting weird? or am I missing something?

Google App Engine/1.3.0
Python 2.5.2 (r252:60911, Apr  7 2009, 17:42:26) 
[GCC 4.1.0]

>>> mycolors = ['red','green','blue']
>>> mycolors.append('black')
>>> print mycolors
['red', 'green', 'blue']

But the expected result is expected.

['red', 'green', 'blue', 'black']

And also the same with the dictionary data type.

Thanks,

Abhinay

Short answer

This is a known bug. Short answer:

  • Include all in one line: mycolors.append('black'); print mycolors
  • Use my free App Engine Console software tool . My code is obtained from the shell, and I fixed this error.
