Create dataframe through Dictionary in pandas

[ift38375]

Hi,

I have given below table and i want to create dataframe of this table using Dictionary:

          2019        2017        2015       2013      2011
qtr1      61000       44900       5000       5000      5000
qtr3      NaN         57000       5000       5000      5000
qtr4      NaN         59000       5000       5000      5000
qtr       NaN         NaN         NaN        NaN       NaN

I am using given below code but no luck :

import pandas as pd
df2 = { 2019 :{ 'qtr1':61000, } ,
        2017 :{ 'qtr1':44900,'qtr3':57000,'qtr4':59000},
        2015 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000},
        2013 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000},
        2011 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000}
        }
ndf = pd.DataFrame(df2)
print(ndf)

How can i declare whole row of "qtr' as NaN here i am confused ?

Append qtr somewhere to the dictionary, e.g.
2011 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000, 'qtr': None}.

The following should probably do what you want.

import pandas as pd
df2 = { 2019 :{ 'qtr1':61000, } ,
        2017 :{ 'qtr1':44900,'qtr3':57000,'qtr4':59000},
        2015 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000},
        2013 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000},
        2011 :{ 'qtr1':5000,'qtr3':5000,'qtr4':5000}
        }
ndf = pd.DataFrame(df2)
ndf = ndf.append(pd.DataFrame(index=['qtr']))
print(ndf)

Output:
        2011    2013    2015     2017     2019
qtr1  5000.0  5000.0  5000.0  44900.0  61000.0
qtr3  5000.0  5000.0  5000.0  57000.0      NaN
qtr4  5000.0  5000.0  5000.0  59000.0      NaN
qtr      NaN     NaN     NaN      NaN      NaN
