    <h2>My Situation</h2> <p>I've installed Microsoft Z3 (<code>Z3 [version 4.3.0 - 64 bit]. (C) 2006</code>) and it's <code>pyc</code> binaries for Python2.</p> <p>I've written an Python3 package which needs access to <code>z3</code> functionality.</p> <p>In order to be able to use the <code>pyc</code> binaries with my Python3 package, I <code>decompyle</code> the <code>z3</code> binaries and applied <code>2to3</code>.</p> <h2>My Problem</h2> <p><code>Int('string')</code> doesn't work because Z3Py isn't able to handle the new <code>&lt;class 'str'&gt;</code> used as <code>'string'</code> argument:</p> <pre><code>&gt;&gt;&gt; import z3; z3.Int('abc') Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; File ".\bin\z3.py", line 2931, in Int return ArithRef(Z3_mk_const(ctx.ref(), to_symbol(name, ctx), IntSort(ctx).ast), ctx) File ".\bin\z3.py", line 72, in to_symbol return Z3_mk_string_symbol(_get_ctx(ctx).ref(), s) File ".\bin\z3core.py", line 1430, in Z3_mk_string_symbol r = lib().Z3_mk_string_symbol(a0, a1) ctypes.ArgumentError: argument 2: &lt;class 'TypeError'&gt;: wrong type </code></pre> <h2>My Questions</h2> <ul> <li>It's a little bit hacky to need to <code>decompyle</code> Z3's <code>*.pyc</code> files first. So, are there any Z3Py source codes available?</li> <li>Is there already an existing Z3Py port to Python3?</li> <li>Any other idea how to get <strong>Z3Py to run with Python3</strong>?</li> </ul> <p>Thanks. - If anything's unclear, please leave a question comment.</p>

    2. CO@Kabie Basically yes, but in that repository there aren't any Python3 compatible versions of the source codes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
