I don’t know if a module exists that acts like the which binary. If you don’t know what which does, I’ll tell you:
- given an argument ( which represents a binary/executable found on PATH ), which tells you the first location of that binary
Here’s the code I’m using:
import os def which(program,additional_dirs=): path = os.environ["PATH"] path_components = path.split(":") path_components.extend(additional_dirs) for item in path_components: location = os.path.join(item,program) if os.path.exists(location): return location return None
The code is pretty straight-forward. The function takes a string as the program name, and an optional parameter that represents additional directories to look in. The default behaviour of this functions is to search the PATH variable.
