0
Python C/C++ 嵌套字典 31008 次浏览

比如原生的dict属性

test=dict()
test['a']=1         # 这个可以实现
test['x']['y']=2    # 这个就会报错

我想生成一个递归字典,如果没有这个键则创建,哪种方法能简洁点,优雅点~~多谢了

This needn't bother with a settled dict, fundamentally. You could slotxo utilize pandas, read_csv, make Device_Name the file, at that point you can legitimately join the two dataframes on their list Device_Name.
