I want to check if a module exists, if it doesn’t I want to install it.
How should I do this?
So far I have this code which correctly prints f
if the module doesn’t exist.
try: import keyring except ImportError: print 'f'

Answer
Here is how it should be done, and if I am wrong, please correct me. However, Noufal seems to confirm it in another answer to this question, so I guess it’s right.
When writing the setup.py
script for some scripts I wrote, I was dependent on the package manager of my distribution to install the required library for me.
So, in my setup.py
file, I did this:
package = 'package_name' try: return __import__(package) except ImportError: return None
So if package_name
was installed, fine, continue. Else, install it via the package manager which I called using subprocess
.
