I want to resample a df from daily measurements to yearly measurements.
I have set a DateTime as the index and tried to resample, but the av_df_130302A df doens't appear in my Variable exploreer and nothing happens. I am not sure what I am doing wrong.
df_130302A = df_130302A.set_index('DateTime') av_df_130302A = df_130302A.resample('Y').sum
