Set value for particular cell in pandas DataFrame using index

Question

Asked by Mitkp At 12 December at 14:40

I've created a pandas DataFrame

df=DataFrame(index=['A','B','C'], columns=['x','y'])

and got this

    x    y
A  NaN  NaN
B  NaN  NaN
C  NaN  NaN

Then I want to assign value to particular cell, for example for row 'C' and column 'x'. I've expected to get such result:

    x    y
A  NaN  NaN
B  NaN  NaN
C  10  NaN

with this code:

df.xs('C')['x']=10

but contents of df haven't changed. It's again only Nan's in dataframe.

Any suggestions?
