Python crawler: Simulate Youdao dictionary translation text

introduction

Preliminary learning of reptiles, writing a script about simulating Youdao dictionary translation text

the code

import urllib.request
import urllib.parse
import json
import time


while True:   
    content  =  input("请输入你想翻译的内容：")
    if content == 'q':
        braek
        
    #url中带—_o会导致{
    
    "errorCode":50}
