    if CategoryID[i] == 1:
        totalN + ReactionTime[i]
        countN + 1
        CorrectResponseNeutral + CorrectResponse[i]

AverageRTNeutral = totalN/countN  
CorrectResponseNeutral = CorrectResponseNeutral/countN

totalD = 0 
countD = 0
CorrectResponseDrug = 0
for i in range(len(CategoryID)):
    if CategoryID[i] == 2:
        totalD + ReactionTime[i]
        countD + 1
        CorrectResponseDrug + CorrectResponse[i]

AverageRTDrug = totalD/countD
CorrectResponseDrug = CorrectResponseDrug/countD
InterferenceScore =  AverageRTNeutral - AverageRTDrug       


output['SubjectID'] = idkey 
output['Session'] = sessionkey
output['Interference Score'] = InterferenceScore
output['Accuracy of Neutral Trials'] = CorrectResponseNeutral
output['Accuracy of Drug Trials'] = CorrectResponseDrug
print('---------- Done calculating endpoints ----------')
outputname=input('What would you like to name your outputfile? (Please include.csv)')

outputdataframe = pd.DataFrame.from_dict([output])
outputdataframe.to_csv(os.path.join('/Users/hem/Desktop/Analysis/DrugStroopAnalyzed',outputname))

嘿，伙计们。我正在尝试编写一个可以计算医疗任务端点的脚本。当我运行程序时，它一直工作，直到它到达脚本的第一个for循环。我很确定存在错误，因为CategoryID没有长度属性。但我也认为应该因为我在开始时将其转换为列表。对于如何解决这个问题，有任何的建议吗？提前谢谢。

好像你忘记了()方法之后的tolist，所以它可以被解析为对方法的调用，而不是方法本身：

CategoryID = dataframe['CategoryID'].tolist()
ReactionTime = dataframe['ReactionTime'].tolist()
CorrectResponse = dataframe['CorrectResponse'].tolist()

TypeError：类型＆＃39;方法＆＃39;的对象没有len（）
