python string to symbolic name

I want to check imported names.

Code:

import fst # empty file fst.py
for s in dir(fst):
    print(s) # got string with symbolic names

Output:

__builtins__
__cached__
__doc__
__file__
__name__
__package__

Now I want to check values of each defined name:

Code:

print(__builtins__)
print(__cached__)
print(__doc__)
print(__file__)
print(__name__)
print(__package__)

Question: How can I "extract" symbolic name from string?

supposed code:

import fst #empty file fst.py
for s i开发者_如何转开发n dir(fst):
    print(s, StrToSym(s)) # this call should be equal to str("__name__", __name__)

Use getattr:

for s in dir(fst):
  print (getattr(fst, s))

Use the getattr function:

print(s, getattr(fst, s))

There's no such thing as a "symbolic name". What module contains is available as its attributes, so getattr(module, name) is what you're looking for.
