Select session does not work with python 2

In select-session.py you recently added an eval on the input when choosing with session to join/start new session/or a plain shell, however on python 2 you get a traceback when using eval on input (which is captured by the exception):

--------------- Example ----------------
#!/usr/bin/python

import os
import sys

choice = 1
choice = int(input("\nChoose 1-9 [1]: "))
sys.stdout.write("Choice %d\n" % choice)

choice = 1
choice = int(eval(input("\nChoose 1-9 [1]: ")))
sys.stdout.write("Choice %d\n" % choice)
---------------------------------------------

$ python2.7 inputtest.py

Choose 1-9 [1]: 2
Choice 2

Choose 1-9 [1]: 2
Traceback (most recent call last):
  File "inputtest.py", line 11, in <module>
    choice = int(eval(input("\nChoose 1-9 [1]: ")))
TypeError: eval() arg 1 must be a string or code object

python3 inputtest.py

Choose 1-9 [1]: 2
Choice 2

Choose 1-9 [1]: 2
Choice 2
