I am using Python2.7. I am learning pandas and was implementing pivot_table. While implementing the example given in pivot_table documentation :
raw_dat
You need remove df:
df
#here df.pivot_table(df,index = ['A','B'], values = 'D',columns = 'C', aggfunc = 'sum')
a = df.pivot_table(index = ['A','B'], values = 'D',columns = 'C', aggfunc = 'sum') print (a) C large small A B bar one 4.0 5.0 two 7.0 6.0 foo one 4.0 1.0 two NaN 6.0
