Using sh.cd to go to the home directory #275

Is there some way to simulate cd (in order to go to the home directory) without giving arguments to sh.cd? Currently:

>>> sh.cd
<bound method Environment.b_cd of {}>
>>> sh.cd()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: b_cd() takes exactly 2 arguments (1 given)

Another question: what other "Environment" methods are there besides cd?

  1. No
  2. Take a look at the source

1 . Maybe it is possible to use os.path.expanduser('~') to provide a cd:

def b_cd(self, path):
    if path:
        os.chdir(path)
    else:
        os.chdir(os.path.expanduser('~'))

2 . Thanks

@rsmith31415 that looks pretty close. I would make path have a default value of None though in the function. Open a PR and I will likely merge it :)

If you think it is that simple to solve, sure.
