Answer 1

It was a dynamically generated class so here is the proper way to grab it. It should work through any changes it does now.

name=wd.find_element_by_css_selector("div.lpi-chart-container").get_attribute('data-chart-init-code-function-name')
pprint(wd.execute_script("return window['"+name+"']();"))

• Arundeep Chohan: Date.UTC(2007,11,19) is the number of seconds after January 1 1970 until December 19 2007.

The function name is variable, you need to get the right one each time:

import re
r = re.findall(r'function (getChartInitJsCode[^(]+)', wd.page_source)
if r:
 pprint(wd.execute_script("return (%s())" % r[0]))
