With open(t_file, 'w', encoding="utf-8") as ef: import asyncioīrowser = await launch(options=.csv') The first link follow seems to work because I get different HTML but the second click gives me the same page, not a download. My attempt to replicate this in Python follows.
Follow the link, "See count total holdings". Note, the link says CSV but it provides an Excel file. The links resolve through JavaScript so I'm using Pyppeteer but I'm not getting the file. If an expression is erroneously treated as function and an error is raised, try setting `force_expr` to `True`, to force pyppeteer to treat the string as expression.\n\n# Examples:\n\nGet a page's `textContent`:\n\n```python\ncontent = await page.evaluate('', force_expr=True)\n```\n\nGet an element's `textContent`:\n\n```python\nelement = await page.querySelector('h1')\ntitle = await page.evaluate('(element) => element.I'm trying to automate downloading the holdings of Vanguard funds from the web. pyppeteer will try to automatically detect if the string is function or expression, but it will fail sometimes. pyppeteer takes string representation of JavaScript expression or function. The equivalent methods to Puppeteer's `$`, `$$`, and `$x` methods are listed below, along with some shorthand methods for your convenience:\n\n| puppeteer | pyppeteer | pyppeteer shorthand |\n|-|-|-|\n| Page.$() | Page.querySelector() | Page.J() |\n| Page.$$() | Page.querySelectorAll() | Page.JJ() |\n| Page.$x() | Page.xpath() | Page.Jx() |\n\n# Arguments of `Page.evaluate()` and `Page.querySelectorEval()`\n\npuppeteer's version of `evaluate()` takes a JavaScript function or a string representation of a JavaScript expression. () and () are also great resources for pyppeteer users.Īwait page.screenshot()\n```\n\nKeyword argument style options (more pythonic, isn't it?):\n\n```python\nbrowser = await launch(headless=True)\n```\n\n# Element selector method names\n\nIn python, `$` is not a valid identifier. One way to do this is to run `pyppeteer-install` command before prior to using this library.įull documentation can be found (). If you don't prefer this behavior, ensure that a suitable Chrome binary is installed. > **Note**: When you run pyppeteer for the first time, it downloads the latest version of Chromium (~150MB) if it is not found on your system.
