Turn cURL Commands into Python Code Instantly with curl2py – A Step‑by‑Step Guide

Introduction

The curl2py command is part of the filestools library and can directly convert a cURL request into equivalent Python code, eliminating the tedious manual copying of headers, cookies, and parameters.

Installation

Install the library via pip: pip install filestools or use a trusted mirror:

pip install filestools -i http://pypi.douban.com/simple/ --trusted-host=pypi.douban.com

Traditional Method

Normally you would open the browser’s developer tools, copy the request headers, cookies, and parameters one by one, and paste them into your script—a process that is error‑prone and time‑consuming.

Using curl2py

1. In the browser, right‑click the request and choose Copy → Copy as cURL (bash) .

2. Paste the copied cURL command into the following Python snippet and run it:

from curl2py.curlParseTool import curlCmdGenPyScript
curl_cmd = """xxx"""
output = curlCmdGenPyScript(curl_cmd)
print(output)

Example

Running the above with a real request to https://xxkol.cn/api/klist generates the following script:

import requests

headers = {
    "authority": "xxkol.cn",
    "sec-ch-ua": "\"Chromium\";v=\"92\", \" Not A;Brand\";v=\"99\", \"Microsoft Edge\";v=\"92\"",
    "accept": "application/json, text/plain, */*",

    "pagesize": "20",
    "page": "2",
    "name": "",
    "follower_start": "",
    "follower_end": "",
    "inter_start": "",
    "inter_end": "",
    "xxpoint_start": "",
    "xxpoint_end": "",
    "platform": "",
    "sex": "",
    "attribute": "",
    "category": "",
    "sort_type": ""
}

res = requests.get("https://xxkol.cn/api/klist", params=params, headers=headers, cookies=cookies)
print(res.text)

Result

Executing the script returns JSON data, which can be inspected with an online JSON formatter (e.g., https://www.sojson.com/ ).

Conclusion

The curl2py tool automates the conversion of web requests into Python code, saving effort and reducing errors, making it a handy utility for anyone working on web scraping or API integration.
