[英]Python | Add 2 of The Same Keys In A Dict
我如何才能將screenshoturl2
的兩個相同的鍵添加到一個dict文件中的screenshoturl2
和screenshoturl1
?
這是我現在的代碼,它可以工作,但它只是添加了第一個screenshoturl1
而不是screenshoturl2
,我不知道如何讓它添加它。 在此處查看答復,以獲取有關我的主題的更多信息,以及可能有用的信息

我希望它刪除screenshots
中的所有內容,並用他們在screenshoturl1
和screenshoturl2
輸入的用戶輸入重新添加,這樣它將刪除screenshots
的占位符之類的所有內容,並且僅將用戶在screenshoturl1
和screenshoturl2
url2中輸入的網址加回2並且幫助會很好。
謝謝!
您可以將值設為一個集合(例如列表或元組)。 為了方便起見,您可以使用defaultdict。 所以如果你想為一個鍵有兩個值:
from collections import defaultdict
multiValueDict = defaultdict(list)
multiValueDict[1].append(1)
multiValueDict[1].append(2)
print(multiValueDict[1])
並輸出:
[1, 2]
如果我理解您在此處嘗試做什么,看起來您希望一次更新一個或兩個URL。
您可以做的是一次瀏覽每個屏幕截圖項目,然后更新或停止。 這樣更容易,並且如果您願意,還可以更新所有這些內容。 這也意味着我們不必問前面有多少人(我們只是在我們不再接受的時候停下來)。
import json
# Load the data
file_name = 'path/to/json/file'
with open(file_name) as fh:
full_data = json.load(fh)
# Dig into the data to find the screenshots
screen_shots = full_data['tabs'][0]['views'][1]['screenshots']
# Loop over each screen shot, updating each one
for number, screen_shot in enumerate(screen_shots):
print("Screenshot", number)
print('\tCurrent data:', screen_shot)
new_url = input(
"\tPlease enter new URL (leave empty and press return to stop): "
).strip()
if new_url:
# Updating the data here will also update the 'full_data' object
# as we are just referencing a part of it, not making copies
screen_shot.update({"url": new_url, "fullSizeURL": new_url})
else:
print("\tAll done!")
break
# Remove all entries which we did not update
screen_shots = screen_shots[:number]
# Save the data
with open(file_name, 'w') as fh:
json.dump(full_data, fh, indent=4)
您可能要查看的其他事情是從函數返回結果,而不是使用全局變量,因為這可能會使大型腳本迅速混淆。
