self.name = [ v[0] for v in rank.values()]

>>> import pandas as pd

>>> df = pd.DataFrame([["jeff", "188B", "us"],["elon", "170B", "us"]])
>>> df
      0     1   2
0  jeff  188B  us
1  elon  170B  us

>>> df = pd.DataFrame([["jeff", "188B", "us"],["elon", "170B", "us"]], columns=["name", "wealth", "nation"])
>>> df
   name wealth nation
0  jeff   188B     us
1  elon   170B     us

data = pd.DataFrame(rank.values(), 
                    columns=[ "name", "wealth", "wealth_delta1", "wealth_delta2", "nationality", "business area" ])
