Check that the Schrodinger python version is at least the value ‘v’. NOTE: Deprecated in favor of get_mmshare_version()


Check that the Schrodinger python version does not exceed ‘v’. NOTE: Deprecated in favor of get_mmshare_version()

schrodinger.version_compatible(minimum, maximum)

Check that the version is between minimum and maximum values. NOTE: Deprecated in favor of get_mmshare_version()

If the current Schrodinger python version is less than the minimum, an Exception will be raised. If the current version is greater than the maximum, a warning will be issued.

schrodinger.get_release_name() str

Return descriptive text name of the current release.

schrodinger.get_bumped_release_version(current_version: str, bump_val: int = 1) str
