[英]how to access several layers of dictionaries and lists nested within each other and collect them into a list
im looking to access the urls of the images in this json file. 我希望访问此json文件中的图像的URL。 However I can only get so far in the nest.
但是我只能在巢中走得这么远。 I got as far as Image which prints out ' "url": //images.... '
我得到的图像打印出“url”:// images ....
{
"devices": [
{
"variants":
[
{
"iMEIPrefix": null,
{
"totalTax": 0,
},
"smartTab": {
"payOffPeriod": 24,
"requiredUpfrontPayment": 0,
},
"pricingForUi": {
"payOffPeriod": 24,
"requiredUpfrontPayment": 0,
},
"memory": "64GB",
"phoneImages": [

],
phoneImages = phone['variants'][0]['phoneImages']
data['image'] = phoneImages
for example im hoping to have this output: 例如我希望有这个输出:
"image": [
"https://xpressphone-backend.herokuapp.com/Apple iPhone XR/xr-black-front.png",
"https://xpressphone-backend.herokuapp.com/Apple iPhone XR/xr-black-back.png"
],
It's not a valid json file, you should remove {"totalTax": 0},
this part or convert into "totalTax": 0
它不是一个有效的json文件,你应该删除
{"totalTax": 0},
这部分或转换为"totalTax": 0
data = {}
phoneImages = [image['url'] for image in phone['devices'][0]['variants'][0]['phoneImages']]
data['image'] = phoneImages
print(data)
O/P: O / P:
{'image': ['//images.ctfassets.net/7bx5buq4osbe/4tfPcjBNmnbWupJ7byONiZ/0f27dc736403c4027bbf13f184ffd4fc/PIXEL3A-BLACK-FRONT.png', '//images.ctfassets.net/7bx5buq4osbe/1UVKkXIBCUPkKJ8ROvFkOO/8f25b2c57bfd774792dfb69ed1d3cc29/PIXEL3A-BLACK-SIDE.png', '//images.ctfassets.net/7bx5buq4osbe/1K2AP67ZhWb9pBtIp3r1sj/755bdc263d4a6e43e8275bea2beb92d3/PIXEL3A-BLACK-BACK.png']}
urls = []
phoneImages = phone['variants'][0]['phoneImages']
for phoneImage in phoneImages:
urls.append = phoneImage['url']
