At the start of your main for loop you have: nghr_targets[pi_drug] = {}. Implementing nested CV in python, thanks to scikit-learn, is relatively straightforward. The nested_lookup package provides many Python functions for working with deeply nested documents. Simillarly, a dictionary is a collection of key: value pairs. You can supply a different default value to dict.get: Choosing an empty dict as default works because you can call get on it again, and it will always return None because it's empty. In the above example, we have created a nested dictionary ‘d’ which has another dictionary inside of it as ‘lang’. Access the elements using the [] syntax. ._3gbb_EMFXxTYrxDZ2kusIp{margin-bottom:24px;text-transform:uppercase;width:100%}._3gbb_EMFXxTYrxDZ2kusIp:last-child{margin-bottom:10px} dict(), you get a new instance of that type. brightness_4 If we want to store information in a structured way, creating a nested dictionary in python can be one of the better options. Dictionary after removal : {‘is’: {‘educational’: 4}, ‘gfg’: {‘best’: 4, ‘good’: 5}, ‘CS’: {}}. To get the value of the key you want, you have to use the get() function using Python. Get Dictionary Value By Key With Get() in Python. I don't have control of constructing the dict unfortunately, it's just passed to me from the framework. Keys of a Dictionary must be unique and of immutable data type such as Strings, Integers and tuples, but the key-values can be repeated and be of any type. Nested Dictionary in Python. If you do not provide the default, it defaults to None . But, rather than accessing elements using its index, you assign a fixed key to it and access the element using the key. ._1EPynDYoibfs7nDggdH7Gq{margin-bottom:8px;position:relative}._1EPynDYoibfs7nDggdH7Gq._3-0c12FCnHoLz34dQVveax{max-height:63px;overflow:hidden}._1zPvgKHteTOub9dKkvrOl4{font-family:Noto Sans,Arial,sans-serif;font-size:14px;line-height:21px;font-weight:400;word-wrap:break-word}._1dp4_svQVkkuV143AIEKsf{-ms-flex-align:baseline;align-items:baseline;background-color:var(--newCommunityTheme-body);bottom:-2px;display:-ms-flexbox;display:flex;-ms-flex-flow:row nowrap;flex-flow:row nowrap;padding-left:2px;position:absolute;right:-8px}._5VBcBVybCfosCzMJlXzC3{font-family:Noto Sans,Arial,sans-serif;font-size:14px;font-weight:400;line-height:21px;color:var(--newCommunityTheme-bodyText)}._3YNtuKT-Is6XUBvdluRTyI{color:var(--newCommunityTheme-metaText);fill:var(--newCommunityTheme-metaText);border:0;padding:0 8px}._3YNtuKT-Is6XUBvdluRTyI:active,._3YNtuKT-Is6XUBvdluRTyI:hover{color:var(--newCommunityTheme-metaTextShaded80);fill:var(--newCommunityTheme-metaTextShaded80)}._3YNtuKT-Is6XUBvdluRTyI:disabled,._3YNtuKT-Is6XUBvdluRTyI[data-disabled],._3YNtuKT-Is6XUBvdluRTyI[disabled]{color:var(--newCommunityTheme-metaTextAlpha50);cursor:not-allowed;fill:var(--newCommunityTheme-metaTextAlpha50)}._2ZTVnRPqdyKo1dA7Q7i4EL{transition:all .1s linear 0s}.k51Bu_pyEfHQF6AAhaKfS{transition:none}._2qi_L6gKnhyJ0ZxPmwbDFK{transition:all .1s linear 0s;display:block;background-color:var(--newCommunityTheme-field);border-radius:4px;padding:8px;margin-bottom:12px;margin-top:8px;border:1px solid var(--newCommunityTheme-canvas);cursor:pointer}._2qi_L6gKnhyJ0ZxPmwbDFK:focus{outline:none}._2qi_L6gKnhyJ0ZxPmwbDFK:hover{border:1px solid var(--newCommunityTheme-button)}._2qi_L6gKnhyJ0ZxPmwbDFK._3GG6tRGPPJiejLqt2AZfh4{transition:none;border:1px solid var(--newCommunityTheme-button)}.IzSmZckfdQu5YP9qCsdWO{cursor:pointer;transition:all .1s linear 0s}.IzSmZckfdQu5YP9qCsdWO ._1EPynDYoibfs7nDggdH7Gq{border:1px solid transparent;border-radius:4px;transition:all .1s linear 0s}.IzSmZckfdQu5YP9qCsdWO:hover ._1EPynDYoibfs7nDggdH7Gq{border:1px solid var(--newCommunityTheme-button);padding:4px}._1YvJWALkJ8iKZxUU53TeNO{font-size:12px;font-weight:700;line-height:16px;color:var(--newCommunityTheme-button)}._3adDzm8E3q64yWtEcs5XU7{display:-ms-flexbox;display:flex}._3adDzm8E3q64yWtEcs5XU7 ._3jyKpErOrdUDMh0RFq5V6f{-ms-flex:100%;flex:100%}._3adDzm8E3q64yWtEcs5XU7 .dqhlvajEe-qyxij0jNsi0{color:var(--newCommunityTheme-button)}._3adDzm8E3q64yWtEcs5XU7 ._12nHw-MGuz_r1dQx5YPM2v,._3adDzm8E3q64yWtEcs5XU7 .dqhlvajEe-qyxij0jNsi0{font-size:12px;font-weight:700;line-height:16px;cursor:pointer;-ms-flex-item-align:end;align-self:flex-end;-webkit-user-select:none;-ms-user-select:none;user-select:none}._3adDzm8E3q64yWtEcs5XU7 ._12nHw-MGuz_r1dQx5YPM2v{color:var(--newCommunityTheme-button);margin-right:8px;color:var(--newCommunityTheme-errorText)}._3zTJ9t4vNwm1NrIaZ35NS6{font-family:Noto Sans,Arial,sans-serif;font-size:14px;line-height:21px;font-weight:400;word-wrap:break-word;width:100%;padding:0;border:none;background-color:transparent;resize:none;outline:none;cursor:pointer;color:var(--newRedditTheme-bodyText)}._2JIiUcAdp9rIhjEbIjcuQ-{resize:none;cursor:auto}._2I2LpaEhGCzQ9inJMwliNO{display:inline-block}._2I2LpaEhGCzQ9inJMwliNO,._42Nh7O6pFcqnA6OZd3bOK{margin-left:4px;vertical-align:middle}._42Nh7O6pFcqnA6OZd3bOK{fill:var(--newCommunityTheme-button);height:16px;width:16px;margin-bottom:2px} Separated from each other by a comma (, ) with the new keys that become!
