I'm having the same issue trying to use ansible:
As with the OP, it works fine from ipython.

The issue is that bpython replaces
sys.stdoutwith an object calledFakeOutputand somewhere down the line in pwntools, tries to blindly use thesys.stdout.filenomethod. According to the standard, this method is not required. The only thing that is required of sys.stdout is awritemethod. That being said, I've created a fix for this as seen in this pull request. It's not the best solution, since FakeInput shouldn't be required to implement this, but it doesn't break anything and allows you to import pwntools. I'd say it's a good compromise. My fix also will correctly return1forsys.stdoutand2forsys.stderr.That being said, logging with pwntools will still be broken, because curtsies does not properly parse the reset escape sequence. Again, I've created a pull request for curtsies to correct this issue as well. With both of these changes, importing pwntools works great on my machine.
