How to Convert Wide Dataframe to Tidy Dataframe with Pandas stack()? This is a good solution though there also is a disadvantage: even if the first key is not available, or the value passed as the dictionary argument to the function is not a dictionary, the function will go from first element to the last one. An elegant way to concatenate lists (your value.keys () lists) into one is using a double-loop list comprehenstion, like this: nested_keys = [ key for val in data.values () This is brute way in which this problem can be solved. If you want to end up a nested dictionary that includes that key pairing anyway like I did, this seems like the easiest solution.
