Answer 1

Using df.set_index and df.T and df.rename_axis df = df.set_index('id').T.rename_axis("Date", axis=1) print(df) Output: Date a b c 1/22/20 1 3 5 1/23/20 2 4 6 1/24/20 3 5 7 1/25/20 4 6 8 If you are a beginner and want to know more about Python the do check out the python for data science course
