python - 将文本从一个文件传输到另一个文件

Question

我在将 dist 参数从输入文件传输到结果文件到输入文件中的相同位置时遇到问题我的代码是：

import requests
import json
import time

with open("query4.txt", "rt") as file:
        data_file = file.read()

with open("result.txt", "w") as f_o:
    for line in data_file.split("\n"):
            for i in range(1):
                    drX, drY, fromX, fromY, dist = line.split(",")

                    url = "https://api.openrouteservice.org/directions?"
                    params = [
                            ["api_key", "my_api_key"],
                            ["coordinates", "%s,%s|%s,%s" % (drY, drX, fromY, fromX)],
                            ["profile", "driving-car"]
                    ]
                    headers = {
                            "Accept": "application/json, application/geo+json,"
                                      "application/gpx+xml, img/png; charset=utf-8"}
                    responce = requests.get(url=url, params=params, headers=headers)
                    print(responce.url)
                    # print(responce.text)
                    result = json.loads(responce.text)
                    print(result)
                    for rows in result["routes"]:
                            print(rows["summary"]["distance"], file=f_o)  # depending on how do you want the result
                            # print(result["routes"])
                            time.sleep(0)

输入样本：

48.94205856,38.48511505,48.94167600,38.49207300,511
46.54586411,30.64417267,46.53338808,30.65455914,1599
50.06436157,31.44526100,50.07415641,31.45929694,1482
50.35911942,30.94097710,50.33576900,30.95166500,2706
50.35837936,30.94162369,50.33576900,30.95166500,2614

作为现在的输出，我与摘要 json 有一段距离，例如

123.2
122.5
221
312.7
212

我想得到这个

123.2 125
122.5 122
221 340
312.7 300
212 220

我用过这个，但它似乎不起作用：

with open("query4.txt") as f:
    input_file = f.read()
    with open("result.txt", "w") as f1:
        for line in input_file.split("\n"):
            for line in f:
                dX, dY, fX, fY, dst = line.split(",")
                if "dst" in line:
                    f1.write(line)

您只需将dist变量添加到打印命令。此外，还有一些改进可以为您的代码带来：

import requests
import json

url = "https://api.openrouteservice.org/directions?"

headers = {"Accept": "application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8"}

with open("query4.txt", "rt") as f_i, open("result.txt", "w") as f_o:

    for line in f_i:
        drX, drY, fromX, fromY, file_dist = line.split(",")

        params = [
                ["api_key", "my_api_key"],
                ["coordinates", "%s,%s|%s,%s" % (drY, drX, fromY, fromX)],
                ["profile", "driving-car"]
        ]

        response = requests.get(url=url, params=params, headers=headers)
        result = json.loads(response.text)

        for rows in result["routes"]:
            f_o.write("{from_api} - {from_file}\n".format(from_api = rows["summary"]["distance"], from_file = file_dist) )
