I am using pyodbc
and I want to know the version of it that I am using.
Apparently I cannot use pyodbc.__version__
because probably the variable is not set.
How else can I figure out the version of the package?
It does have the version info, just use .version
:
In [4]: pyodbc.version
Out[4]: '3.0.10'
The pip show command would also get it for you:
In [54]: pip.main(["show","pyodbc"])
---
Metadata-Version: 1.1
Name: pyodbc
Version: 3.0.10
Summary: DB API Module for ODBC

You could redirect stdout and parse the output:
import pip
import sys
if sys.version_info.major >= 3:
from io import StringIO
else:
from StringIO import StringIO
def get_version(package):
f = StringIO()
sys.stdout = f
pip.main(["show", package])
sys.stdout = sys.__stdout__
return next((line.split(":", 1)[1].strip()
for line in f.getvalue().splitlines() if line.startswith("Version")), "No match")
But an easier way is to use pkg_resources
, if you look at the source for show, you can see how it is gathered:
from pip._vendor import pkg_resources
def get_version(package):
package = package.lower()
return next((p.version for p in pkg_resources.working_set if p.project_name.lower() == package), "No match")
To use it just pass the package name:
In [57]: get_version("pyodbc")
Out[57]: '3.0.10'
In [58]: get_version("pandas")
Out[58]: '0.17.1'
In [59]: get_version("requests")
Out[59]: '2.9.1'
In [60]: get_version("foobar")
Out[60]: 'No match'
You can easily extend it to get different info using similar logic to the show command.
To get a short report about the module, including its version, run:
pip show pyodbc
in a command prompt (e.g. Windows cmd
). This works even for modules without a __version__ attribute.
You can use this command (from terminal)
pip freeze | grep pyodbc
For installation of pip (debian, ubuntu):
apt-get install python-pip
