Pandas Dataframe Sort On Column Raises Keyerror On Index

I have the following dataframe, df: peaklatency snr 0 52.99 0.0 1 54.15 62.000000 2 54.12 82.000000 3 54.64 52.000000 4 54.5

Solution 1:

The by keyword to sort_values expects column names, not the actual Series itself. So, you'd want:

In [23]: df.sort_values('snr')
Out[23]: 
   peaklatency   snr
0        52.99   0.0
4        54.57  42.0
3        54.64  52.0
1        54.15  62.0
5        54.13  72.0
2        54.12  82.0
