How do I get select the option from drop down list?

I am trying to automate form filling process using selenium in python. I want to select "Consumer Health Plant" option.

<div class="select-placeholder">
    <span aria-live="polite" id="Select_1_placeholder" class="select-placeholder-text" role="textbox" aria-label="Consumer Health Plant">Consumer Health Plant</span>
    <i class="ms-Icon ms-Icon--ChevronDown select-placeholder-arrow forms-icon-size14x14" role="presentation" aria-hidden="true"></i>
</div>
