I have recently started using selenium with python and stuck with the below problem. It may be simple but I have tried a lot while searching through different answers but could not solve it.
I want to click the 2nd text box with class name 'param-text-input text-input numeric-value'

```
    <div class="bet-widget-main-row-right">
      <div class="bet-widget-main-content">
        <div class="bet-params">
           <div class="param-wrapper">
              <span class="param-label">Label1</span>
              <div class="param-input -desktop">
                <div class="param with-error">
                  <span class="param-input-wrapper">
                    <span class="param-currency numeric-value">£</span>
                    <input type="text" class="param-text-input text-input numeric-value" value=".04" tabindex="0" size="3" maxlength="11">
                  </span>
                </div>
              <div class="param-input_ticks"></div>
            </div>
          </div>
          <div class="param-wrapper">
            <span class="param-label">Label2</span>
            <div class="param-input -desktop">
              <div class="param">
                <span class="param-input-wrapper">
                  <input type="text" class="param-text-input text-input numeric-value" value="2.18" tabindex="0" size="4" maxlength="8">
                </span>
              </div>
              <div class="param-input_ticks"></div>
            </div>
          </div>
        </div>
      </div>
    <div class="bet-submit"><button class="confirm-bet-button -accented micro-button" type="submit" disabled="" tabindex="0"><span>Button1</span></button></div></div>

```

I have tried multiple solutions but none work:

```
self.driver.find_element_by_xpath("//[@class='param-text-inp‌​ut.text-input.numeri‌​c-value'][2]").clear‌​() 

self.driver.find_element_by_css_selector("[input.param-text-‌​input.text-input.num‌​eric-value][2]").cle‌​ar() 

self.driver.find_element_by_xpath("//input[@class='param-tex‌​t-input'][2]").clear‌​()

```

Any pointers/help is appreciated.
