Sending a variable in python payload - http client : <p>I'm trying to send a variable in python using a payload created by postman, I tried using {{}} and it 
didn't work for me, the place where I need the variable is indicated as VARIABLE_SPOT, please let me know what I did wrong in order to send a variable and not a text.</p>

<pre><code>payload = "{\r\n    \"some_key\": \"VARIABLE_SPOT\",\r\n }
</code></pre>
