Question

def score():
    edu = df.dummy
    if edu == 1:
        score= 10
    elif edu == 2:
        score= 30
    elif edu == 3:
        score= 80
    elif edu == 4:
        score= 100
    elif edu == 5:
        score= 125
    elif edu == 6:
        score= 150
    elif edu == 7:
        score= 200
    else: return score

发生的错误：系列的真值不明确。使用a.empty，a.bool（），a.item（），a.any（）或a.all（）。如何使用Multiple if else条件返回整数值

Answer 1

首先，如果edu大于7，则分数不分配任何值。所以你不能返回分数。

而且，您可以尝试df = pd.get_dummies(df, columns=['type'])。

Answer 2

您只需要清除else语句就可以了

def scores():
    score=0
    edu = df.dummy

    if edu == 1:
        score= 10
    elif edu == 2:
        score= 30
    elif edu == 3:
        score= 80
    elif edu == 4:
        score= 100
    elif edu == 5:
        score= 125
    elif edu == 6:
        score= 150
    elif edu == 7:
        score= 200
    return score

Answer 3

def score(edu):
    if edu == 1:
        score= 10
    elif edu == 2:
        score= 30
    elif edu == 3:
        score= 80
    elif edu == 4:
        score= 100
    elif edu == 5:
        score= 125
    elif edu == 6:
        score= 150
    elif edu == 7:
        score= 200
    else:
        score=0
return score

现在，在调用函数时，将数据帧传递为得分（df.dummy）。

Answer 4

def edu_score():
    edu = df.dummy
    edu_score=[]
    for i in edu:
        if(i == 1):
            score = 10
        elif(i == 2):
            score = 30
        elif(i == 3):
            score = 80
        elif(i == 4):
            score = 100
        elif(i == 5):
            score = 125
        elif(i == 6):
            score = 150
        elif(i == 7):
            score = 200
        edu_score.append(score)
    return edu_score
