How do I change a single index value in pandas dataframe?
You want to do something like this:
as_list = df.index.tolist()idx = as_list.index('Republic of Korea')as_list[idx] = 'South Korea'df.index = as_listBasically, you get the index as a list, change that one element, and the replace the existing index.
@EdChum's solution looks good.Here's one using rename, which would replace all these values in the index.
energy.rename(index={'Republic of Korea':'South Korea'},inplace=True)Here's an example
>>> example = pd.DataFrame({'key1' : ['a','a','a','b','a','b'], 'data1' : [1,2,2,3,nan,4], 'data2' : list('abcdef')})>>> example.set_index('key1',inplace=True)>>> example data1 data2key1 a 1.0 aa 2.0 ba 2.0 cb 3.0 da NaN eb 4.0 f>>> example.rename(index={'a':'c'}) # can also use inplace=True data1 data2key1 c 1.0 ac 2.0 bc 2.0 cb 3.0 dc NaN eb 4.0 f
Try This
df.rename(index={'Republic of Korea':'South Korea'},inplace=True)
