Question

我想使用函数在数据框中添加一行

features = pd.read_csv("Work.csv")

这是函数：

def classify(Res,O,S,R,Rear,F,L,B):    
     features = pd.DataFrame(np.array([[Res,O,S,R,Rear,F,L,B]]), 
                      columns=['Resolution','OS','Storage','RAM',
                       'RearCamera','FrontCamera','LoudSpeaker','Battery'])\
                  .append(features, ignore_index=True)

当我将该函数称为：

classify(19283,"lolipop","fr","gg","ff",0,0,0)

我收到以下错误：

 ---------------------------------------------------------------------------
UnboundLocalError                         Traceback (most recent call last)
<ipython-input-4-7c16987ef1b2> in <module>()
----> 1 classify(19283,"lolipop","fr","gg","ff",0,0,0)

<ipython-input-3-c620ec52544a> in classify(Res, O, S, R, Rear, F, L, B)

----> 3     features = pd.DataFrame(np.array([[Res,O,S,R,Rear,F,L,B]]), columns=['Resolution','OS','Storage','RAM','RearCamera','FrontCamera','LoudSpeaker','Battery']).append(features, ignore_index=True)

UnboundLocalError: local variable 'features' referenced before assignment

我该如何解决？

UnboundLocalError：赋值之前引用了局部变量“功能”
