问题 Using a very basic program to search up a query on a website and print out the search results, why do I get a 502 error? import requests from bs4 import BeautifulSoup import re def main(): url = "https://www.last10k.com/Search" dat = {'q':'goog'} resp = requests.get(url, params=dat) print(resp.content) 回答1: Define a User-Agent header. Like this: import requests def main(): url = "https://www.last10k.com/Search" dat = {'q':'goog'} resp = requests.get(url, params=dat, headers={'User-Agent':

问题 I am trying to create a pdf puller from the Australian Stock Exchange website which will allow me to search through all the 'Announcements' made by companies and search for key words in the pdfs of those announcements.

问题 Here is the Code and sample results , I just want the first column of the table ignoring the rest.

问题 I set my cronjob to call my script at particular time( ex- 2 4 5 10 * python3 mayank/exp/test.py ). When my test.py is called I'm activating the virtualenv within my test.py script as follows. activate = "/home/myserver/schedule_py3/bin/activate_this.py" exec(open(activate).read()) After activating the virtual environment(which has python3 in it and the packages needed to run the script), I'm trying to import requests it is showing me error as:- File "schedule_module/Schedule/notification

问题 Is a function like: async def f(x): time.sleep(x) await f(5) properly asynchronous/non-blocking? Is the sleep function provided by asyncio any different? and finally, is aiorequests a viable asynchronous replacement for requests? (to my mind it basically wraps main components as asynchronous) https://github.com/pohmelie/aiorequests/blob/master/aiorequests.py 回答1: The provided function is not a correctly written async function because it invokes a blocking call, which is forbidden in asyncio.

问题 I've been looking around for ways to upload large file with additional data, but there doesn't seem to be any solution. To upload file, I've been using this code and it's been working fine with small file: with open("my_file.csv", "rb") as f: files = {"documents": ("my_file.csv", f, "application/octet-stream")} data = {"composite": "NONE"} headers = {"Prefer": "respond-async"} resp = session.post("my/url", headers=headers, data=data, files=files) The problem is that the code loads the whole

问题 Using proxy connection (HTTP Proxy : 10.3.100.207, Port 8080). Using python's request module's get function, getting following error: "Unable to determine SOCKS version from socks://10.3.100.207:8080/" 回答1: Try export all_proxy="socks5://10.3.100.207:8080" if you want to use socks proxy. Else export all_proxy="" for no proxy. Hope This works. :D 回答2: I resolved this problem by removing "socks:" in_all_proxy. 来源： https://stackoverflow.com/questions/39906836/unable-to-determine-socks-version
