conan_version

Variable of type Version (see below) that defines the version of the Conan client. You can use it in your recipes like:

from conan import conan_version

class pkg(ConanFile):
    ...
    def generate(self):
        if conan_version.major == "1":
            print("Running Conan 1.X")

Version

Available since: 1.46.0

constructor

def __init__(self, value: str):

Construct a Version object from a string. It supports basic version comparison between objects, like for example:

compiler_lower_than_12 = Version(str(self.settings.compiler.version)) < "12.0"

Please note this is not an implementation of semver, as users may use any pattern in their versions. It is just a helper to parse “.” or “-” and compare taking into account integers when possible.
