I have a DataFrame, df based on an imported csv-file, in order to be able to update data as new dataset become available.
Unnamed: 2 Unnamed: 3 Unnamed: 4 Unnamed: 5
1 NO1 NaN NO2 NaN
2 Up Down Up Down
3 0 0 0 0
4 0 0 0 0
In my dataset, the "NO1" is two merged cells with two sub-categories "Up" & "Down" - I want to combine the "NO1" with both "Up" and "Down" into headers with the text "NO1 Up" & "NO1 Down", etc.
What I want to end up with is:
NO1 Up NO1 Down NO2 Up NO2 Down
0 0 0 0 0
1 0 0 0 0
2 0 0 0 0
3 0 0 0 0
You can TRY:
df.columns = (df.iloc[0].ffill() + ' ' + df.iloc[1]).values
df = df[2:]
