我從網(wǎng)上人類患病icd-11分類下載了一個(gè)json文件，該數(shù)據(jù)最多有8層嵌套，例如：? "name":"br08403",? ? "children":[? ? {? ? ? ? "name":"01 Certain infectious or parasitic diseases",? ? ? ? "children":[? ? ? ? {? ? ? ? ? ? "name":"Gastroenteritis or colitis of infectious origin",? ? ? ? ? ? "children":[? ? ? ? ? ? {? ? ? ? ? ? ? ? "name":"Bacterial intestinal infections",? ? ? ? ? ? ? ? "children":[? ? ? ? ? ? ? ? {? ? ? ? ? ? ? ? ? ? "name":"1A00? Cholera",? ? ? ? ? ? ? ? ? ? "children":[? ? ? ? ? ? ? ? ? ? {? ? ? ? ? ? ? ? ? ? ? ? "name":"H00110? Cholera"? ? ? ? ? ? ? ? ? ? }我嘗試使用以下代碼：def flatten_json(nested_json):? ? """? ? ? ? Flatten json object with nested keys into a single level.? ? ? ? Args:? ? ? ? ? ? nested_json: A nested json object.? ? ? ? Returns:? ? ? ? ? ? The flattened json object if successful, None otherwise.? ?
