For sake of simplicity  maybe you should consider using the Requests library   An example with json response content would be something like   import requests r   requests get  https   github com timeline json   r json     If you look for further information  in the Quickstart section  they have lots of working examples   EDIT   For your specific curl translation   import requests url    https   www googleapis com qpxExpress v1 trips search key mykeyhere  payload   open  request json   headers     content-type    application json    Accept-Charset    UTF-8   r   requests post url  data payload  headers headers

curl -d  request json --header  Content-Type  application json  https   www googleapis com qpxExpress v1 trips search key mykeyhere   its python implementation be like  import requests  headers          Content-Type    application json      params           key    mykeyhere       data   open  request json   response   requests post  https   www googleapis com qpxExpress v1 trips search   headers headers  params params  data data    NB  Original query string below  It seems impossible to parse and  reproduce query strings 100  accurately so the one below is given  in case the reproduced version is not  correct     response   requests post  https   www googleapis com qpxExpress v1 trips search key mykeyhere   headers headers  data data    check this link  it will help convert cURl command to python php and nodejs

Some background  I went looking for exactly this question because I had to do something to retrieve content  but all I had available was an old version of python with inadequate SSL support  If you re on an older MacBook  you know what I m talking about  In any case  curl runs fine from a shell  I suspect it has modern SSL support linked in  so sometimes you want to do this without using requests or urllib2   You can use the subprocess module to execute curl and get at the retrieved content   import subprocess      response  contains a   byte with the retrieved content     use  -s  to keep curl quiet while it does its job  but    it s useful to omit that while you re still writing code    so you know if curl is working response   subprocess check output   curl    -s   baseURL   page num      Python 3 s subprocess module also contains  run   with a number of useful options  I ll leave it to someone who is actually running python 3 to provide that answer
