将文本从一个文件传输到另一个文件

Question

我将dist参数从输入文件传输到结果文件到输入文件所在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

作为输出，现在我与汇总json等有一段距离

123.2
122.5
221
312.7
212

我想要这个

123.2 125
122.5 122
221 340
312.7 300
212 220

我用了这个，但是似乎不起作用：

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)

您只需要将dist变量添加到print命令。 此外，还可以对代码进行一些改进：

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) )
