Python - AttributeError：'dict'对象没有属性'replace'

Question

每当我运行下面的代码时，我都会收到此错误：

AttributeError: 'dict' 对象没有属性 'replace'

我不确定如何解决这个问题。我想搜索 json 文件并找到“屏幕截图包”并将其替换为用户输入，但我得到了那个错误。

我的代码：

numberofscreenshots = input("How much screenshots do you want?: ")

if numberofscreenshots == "1":

    screenshoturl = input("Link to screenshot: ")

    with open('path/to/json/file','r') as f:
        data = f.read()

    data = json.loads(data)

    # Check the data before.
    print( data['tabs'][0]['views'][1]['screenshots'] )

    # Overwrite screenshots placeholders in template file if more then one.
    data['tabs'][0]['views'][1]['screenshots']  =  data['tabs'][0]['views'][1]['screenshots'][0]

    # Check after to make sure it worked.
    print( data['tabs'][0]['views'][1]['screenshots'] )

    # Now search for the screenshot option and add users input.
    screenshotplaceholdertext = {"Screenshot URL 1":screenshoturl}
    for removescreenshotplaceholders in data:
        for screenshotplaceholder, removescreenshotplaceholder in screenshotplaceholdertext.items():
            removescreenshotplaceholders = removescreenshotplaceholders.replace(screenshotplaceholder, removescreenshotplaceholder)
        data.replace(removescreenshotplaceholders)

    # Write data to JSON file.
    with open('path/to/json/file', 'w') as f:
        f.write(json.dumps(data))
else:
    print("Something went wrong.")

任何帮助都会很好。谢谢！

您似乎只是想用screeenshoturl 替换键"Screenshot URL" 的值。如果是这样，那你就大错特错了。试试这个：

with open('path/to/json/file','r') as f:
    data = json.loads(f.read())

# Check the data before.
try:
    data['tabs'][0]['views'][1]['screenshots'][0]
except ValueError:
    print("No Screenshots")

# Overwrite screenshots placeholders.
data['tabs'][0]['views'][1]['screenshots']  =  data['tabs'][0]['views'][1]['screenshots'][0]

#from the error, I'm getting that data['tabs'][0]['views'][1]['screenshots']
#is now a dict, so there should only be one "Screenshot URL" key so no need
#to do any loops here, just replace the key.
data['tabs'][0]['views'][1]['screenshots'].update({"Screenshot URL":screenshoturl})

with open('path/to/json/file', 'w') as f:
    f.write(json.dumps(data))
