Create Pandas Dataframe

index = {'California': 2000, 'California': 2010, 'New York': 2000, 'New York': 2010, 'Texas': 2000, 'Texas': 2010}

population=[23434,56566,76766,546546,45345,56546]

Any method to create data frame in python(pandas) like this:  

state Year population 
California  2000 23434 
            2010 56566 
New York    2000 76766 
            2010 546546 
Texas       2000 45345 
            2010 56546

Your index is broken, because dictionary has always unique keys in python.

For MultiIndex is possible use MultiIndex.from_product, but length of MultiIndex has to be same like length of population list:

mux = pd.MultiIndex.from_product([['California','New York','Texas'], 
                                  [2000, 2010]], names=['state', 'year'])
population=[23434,56566,76766,546546,45345,56546]
df = pd.DataFrame({'population':population}, index=mux)
print (df)
                 population
state      year            
California 2000       23434
           2010       56566
New York   2000       76766
           2010      546546
Texas      2000       45345
           2010       56546

print (len(mux))
6
print (len(population))
6
