    <p>Not directly possible because <a href="https://stackoverflow.com/questions/4869770/why-does-python-assignment-not-return-a-value">assignment doesn't return anything in python</a> but with a bit of hack if you really want.</p> <pre><code>def main(): def f(): nonlocal x x = input() return x x = '' print("Sin(" + f() + ")") </code></pre> <p>This example is an idea about how you can do it. Instead of <code>nonlocal</code> you can have other hacks like mutable objects passed directly to give you more control over where you want the value to be stored.</p> <p><strong>By mutable objects</strong></p> <p>As has been mentioned in comments it is not totally safe and you will need some changes before using this code. It is just meant as an example. Till it becomes clear what the OP actually wants I'll leave it as it is.</p> <pre><code>def main(): def f(x): x[0] = input() return x[0] x = [''] print("Sin(" + f(x) + ")") </code></pre> <p><strong>EDIT2 - Avoiding echo of newline like in case of input()</strong></p> <p>If you want to avoid newline to be echoed then you should see <a href="https://stackoverflow.com/questions/3523174/raw-input-in-python-without-pressing-enter">this</a>. Then make a function to build the desired input into a nonlocal(or global) variable as per your requirements. Here you'll have to do some hackery to define another character at which the variable will be built completelty. Then using the function call between two print statements should give you the desired behavior. The variable returned by the function will have to be printed explicitly as nothing will be echoed. </p>

    2. CO@Aseem Bansal it's a tricky way but it seems not answering my question cause python first starts input command then print what is inputed!

    3. CO@HamidFzM So you want them to run in parallel? Or print, then input then print? If the latter then the only way I can think of is two print statements and input between these statements.

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.
