如何从字典列表中删除文本

Question

词典列表如下

[{'title': 'XXX#1092', 'views': '1,983,228 views'}, {'title': 'xxEP#1091', 'views': '2,559,581 views'}, {'title': 'xx', 'views': '183,545 views'}, {'title': ' Official Music Video', 'views': '439,534 views'}]

如何从 views 和 , 中删除 views 键，预期输出

[{'title': 'XXX#1092', 'views': '1983228'}, {'title': 'xxEP#1091', 'views': '2559581'}, {'title': 'xx', 'views': '183545'}, {'title': ' Official Music Video', 'views': '439534'}]

Answer 1

d = [{'title': 'XXX#1092', 'views': '1,983,228 views'}, {'title': 'xxEP#1091', 'views': '2,559,581 views'}, {'title': 'xx', 'views': '183,545 views'}, {'title': ' Official Music Video', 'views': '439,534 views'}]

for k in d:
    k["views"] = k["views"].replace(",","").replace("views","").strip()

print(d)

[{'title': 'XXX#1092', 'views': '1983228'},
 {'title': 'xxEP#1091', 'views': '2559581'},
 {'title': 'xx', 'views': '183545'},
 {'title': ' Official Music Video', 'views': '439534'}]

Answer 2

videos = [
    {'title': 'XXX#1092', 'views': '1,983,228 views'},
    {'title': 'xxEP#1091', 'views': '2,559,581 views'},
    {'title': 'xx', 'views': '183,545 views'},
    {'title': ' Official Music Video', 'views': '439,534 views'}
]

for video in videos:
    video["views"] = "".join(filter(str.isdigit, video["views"]))

print(videos)

输出：

[{'title': 'XXX#1092', 'views': '1983228'}, {'title': 'xxEP#1091', 'views': '2559581'}, {'title': 'xx', 'views': '183545'}, {'title': ' Official Music Video', 'views': '439534'}]
