title: Why installing package and module not same in Python?
body: <p>I want to install the Biopython module. So I used the command <code>sudo apt-get install python-biopython</code>. That installs the <strong>package</strong>. Now if I type <code>import Bio</code> in Python, the compiler cannot find the <strong>module</strong> giving <code>ImportError: no module named Bio</code>. Doesn't installing the package imply installing the module? </p>
