title: Python: How to get dropdown for options when typing code?
body: <p><em>A very quick beginner question:</em></p>
  <p>How do you trigger the dropdown for available options for arguments, in a called function/module, when typing code in Python? I'm using the Spider environment.</p>
  <p>This is for example regarding the <strong>yfinance</strong> module, where when typing the code, I would like to be able to press &quot;ESC&quot;, and then receive the various options that I can choose from, e.g. the different options regarding intervals:</p>
  <p><strong>Example:</strong>
  apple = yf.download('AAPL', start=start, end=end, <strong>interval='1wk'</strong>)</p>
  <p>The valid intervals for yfinance are:
  &quot;1m,2m,5m,15m,30m,60m,90m,1h,1d,5d,1wk,1mo,3mo&quot;.</p>
  <p>So, I would like to be able to choose from these options from a dropdown when typing that argument.</p>
  <p>Is this a certain environment/package I need to install to enable this, or am I actually requesting a functionality that does not exist for all modules?</p>
  <p>Best, Nic</p>
