Question

我想将列表的内容写入文件。该列表包含从google api地方照片请求的每张照片的内容。当我尝试将列表的内容写入文件时，所有文件最终都带有同一张照片

这是我尝试写入文件的代码任何人都可以帮助

from flask import render_template
import urllib.parse
import requests

import json
import imghdr
import io
import os

@app.route("/NearbyShops")
def NearbyShops():


    final_url = nearby_search_url + urllib.parse.urlencode({'location':'34.015353,-6.830001',
                                                            'radius':'1500',
                                                            'type':'restaurant',
                                                            'key':''})
    places_req = requests.get(final_url)
    places_req.text
    results = json.loads(places_req.text)
    list_photo_reference = []
    list_name = []
    new_list_name= []
    list_requests = []
    lent_list_rq=len(list_requests)
    lent = len(results)


    for i in range(lent):
        for ph in results["results"][i]["photos"]:
            list_photo_reference.append(ph["photo_reference"])

    for n in results["results"]:
       list_name.append(n["name"])

    for ref in list_photo_reference:
        photo_final_url = photos_url + urllib.parse.urlencode({'maxwidth' :'350', 
                                                               'photoreference' :ref,
                                                               'key':''})
        photos_req = requests.get(photo_final_url)
        list_requests.append(photos_req.content)


    for rq,name in zip(list_requests,list_name):
            photo_name= name.replace(" ","_") + "." + imghdr.what("", rq)

            photo_dir = "App/static/photos/" + photo_name

            with open(photo_dir, "wb+") as f:
                f.write(rq)
                f.close()


    image_name = os.listdir('App/static/photos')

    return render_template('NearbyShops.html', title='Nearby Shops',image_name=image_name)

您的代码说：

对于每个请求（或任何ValueError Traceback (most recent call last) <ipython-input-1-1e9eee4e6961> in <module> 17 from object_detection.utils import ops as utils_ops 18 ---> 19 if StrictVersion(tf.__version__) < StrictVersion('1.9.0'): 20 raise ImportError('Please upgrade your TensorFlow installation to v1.9.* or later!') ~/anaconda3/envs/tensorflow_cpu/lib/python3.7/distutils/version.py in __init__(self, vstring) 38 def __init__ (self, vstring=None): 39 if vstring: ---> 40 self.parse(vstring) 41 42 def __repr__ (self): ~/anaconda3/envs/tensorflow_cpu/lib/python3.7/distutils/version.py in parse(self, vstring) 135 match = self.version_re.match(vstring) 136 if not match: --> 137 raise ValueError("invalid version number '%s'" % vstring) 138 139 (major, minor, patch, prerelease, prerelease_num) = \ ValueError: invalid version number '1.13.0-rc1'），请将所述请求写入rq中的每个文件。

因此，计算机完全可以做到这一点，最终您将相同的请求/照片写入所有这些文件。

您可能想遍历list_name对：

(photo, file)

这要求for rq, name in zip(list_requests, list_name): photo_name = ... ...和list_requests的长度相等。

将列表的每个元素写入每个文件
