ACCEPTED ANSWER

You can do:

$ pip install "package>=0.2,<0.3"

And pip will look for the best match, assuming the version is at least 0.2, and less than 0.3.

This also applies to pip requirements files. See the full details on version specifiers in PEP 440.

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

For clarification, each two lines in a pair are equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

you can also use:

pip install package==0.5.*

which is more consistent and easy to read.
