我正在尝试使用pd.pivot_table创建数据透视表.

df1=df.pivot('Partner','Year','Value')

没有问题,并产生一个表

Year                        2011       2012       2013       2014
Partner                                                            
Albania                   0.000693   0.000663        NaN        NaN
Areas, nes                0.002310   0.014177   0.492017   0.633261 
Armenia                        NaN   0.000145        NaN        NaN
Belgium                   0.390415   0.400312   0.493444   0.643490
Brazil                    0.000231   0.000362   0.000518   0.000234
China                     0.024488   0.000443   0.000085   0.000052
Colombia                  0.425991   0.447333   0.488582   0.538809

但是创建my_pivot;

def my_pivot(rows, values, aggfunc, plt=True):
    dfp = df
    piv = pivot_table(dfp, values=values, rows=rows, cols=cols,     aggfunc=aggfunc)
    print piv
    if plt: 
        plot(piv)
        show()


my_pivot(values = df['Value'], rows=df['Partner'], cols=df['Year'], aggfunc=np.sum,plt=True)

产生错误;

TypeError: my_pivot() got an unexpected keyword …
