我刚安装的Python模块:construct并statlib用setuptools这样的:

# Install setuptools to be able to download the following
sudo apt-get install python-setuptools

# Install statlib for lightweight statistical tools
sudo easy_install statlib

# Install construct for packing/unpacking binary data
sudo easy_install construct

我希望能够(以编程方式)检查他们的版本.是否python --version可以从命令行运行？

我的python版本是2.7.3.
