从字典python移除\n

Question

我的字典如下所示：

'{\n  "bindings": [\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/browser"\n    },\n    {\n      "members": [\n        "serviceAccount:admin-user@linuxacademy-3.iam.gserviceaccount.com",\n        "user:rohithmn03@gmail.com"\n      ],\n      "role": "roles/owner"\n    },\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/viewer"\n    }\n  ],\n  "etag": "BwVvsH-HhI0=",\n  "version": 1\n}\n'

我需要从中删除\n； 但是strip()不起作用。在

我们有没有别的办法把它取下来。。！？在

谨致问候， 罗希思

假设您有一个JSON字符串，那么您可能应该使用json模块：

import json
my_dict = json.loads('{\n  "bindings": [\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/browser"\n    },\n    {\n      "members": [\n        "serviceAccount:admin-user@linuxacademy-3.iam.gserviceaccount.com",\n        "user:rohithmn03@gmail.com"\n      ],\n      "role": "roles/owner"\n    },\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/viewer"\n    }\n  ],\n  "etag": "BwVvsH-HhI0=",\n  "version": 1\n}\n')

那么你就有了它作为一本真正的字典，你可以随心所欲地使用它。如果要打印时不使用换行符，可以：

^{pr2}$

或者你可以把它当作一个dict，这取决于你想通过删除新行来完成什么。在

{不过，如果你真的想在cd2中使用}的话，你就可以使用

'{\n  "bindings": [\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/browser"\n    },\n    {\n      "members": [\n        "serviceAccount:admin-user@linuxacademy-3.iam.gserviceaccount.com",\n        "user:rohithmn03@gmail.com"\n      ],\n      "role": "roles/owner"\n    },\n    {\n      "members": [\n        "user:rohithmn3@gmail.com"\n      ],\n      "role": "roles/viewer"\n    }\n  ],\n  "etag": "BwVvsH-HhI0=",\n  "version": 1\n}\n'.replace('\n', '')
