AttributeError: 'float' object has no attribute 'find'

Question

我想找到学位持有者。 以下代码导致 AttributeError: 'float' object has no attribute 'find' 而且我不知道如何修复它：

edu = Edu_data

# Function to identify degree
def degree(x):
    #if x.find('Bachelor') != -1 or x.find("Bachelor's") != -1 or x.find('BS') != -1 or x.find('bs') != -1 or x.find('Bs') != -1 or x.find('Bachelors') != -1 or x.find('Undergraduate') != -1 or x.find('graduated')!= -1 or x.find('BSE')!= -1 or x.find('Enginee') != -1 or x.find('BCS') != -1:
    if x.find('Bachelor') != -1 or x.find("Bachelor's") != -1 or x.find('BS') != -1 or x.find('bs') != -1:
        return(1)
    if x.find('Master') != -1 or x.find("Master's") != -1 or x.find('M.S') != -1 or x.find('MS') != -1 or x.find('MPhil') != -1 or x.find('MBA') != -1 or x.find('MicroMasters') != -1 or x.find('MSc') != -1 or x.find('MSCS') !=-1 or x.find('MSDS')!=-1:
        return(2)
    if x.find('PhD') != -1 or x.find('P.hd') != -1 or x.find('Ph.D') != -1 or x.find('ph.d') != -1:
        return(3)
    else:
        return(0)

    
# Create degree column
edu['deg'] = list(map(degree, edu['Last_degree']))

edu

错误的完整回溯：

AttributeError: 'float' object has no attribute 'find'

Answer 1

图像是否显示了您的所有数据。数据框的

Last_degree

列中的某处是否有可能包含

float

？

如果是，请更改此行：

edu['deg'] = list(map(degree, edu['Last_degree']))

到

edu['deg'] = list(map(degree, edu['Last_degree'].astype(str)))

Answer 2

由于 Nan 值，通过用某些东西替换来删除它们
