python根据list设置字典嵌套内字段的值

Question

print("Hello, World!");
info = {}
def setInfo():
    global info
    list = ['desc', 'id']

print(info["desc"]["id"])

如何根据list设置info字典内id的值

Answer 1

迭代逐步创建嵌套字典，在最后一层字典中设置值

info = {}

def setInfo():
    global info
    lst = ['desc', 'id']
    current_dict = info
    
    for key in lst[:-1]:
        if key not in current_dict:
            current_dict[key] = {}
        current_dict = current_dict[key]
    
    current_dict[lst[-1]] = "your_value"

setInfo()
print(info["desc"]["id"])
