AttributeError: 'str' object has no attribute 'astype'

Question

python 和 pandas 的新排序。我确定我犯了很多 python 和编程犯罪。该脚本在我的个人电脑上运行，但我的工作电脑运行运行。但是我的 google-fu 很弱，无法找到让它正常工作的解决方案，也无法找出 iv 以前工作时做错了什么。我收到此错误

Traceback (most recent call last):

这是代码部分。

   machine_refactory_loc=df.columns.get_loc(1629)
   machine_refactory=df.iloc[0:,(machine_refactory_loc):(machine_refactory_loc+2)]
   machine_refactory=machine_refactory.astype(str)
   machine_refactory.rename(columns = {1629:'Material'}, inplace = True) ## or Brick(1),Block(0)
   machine_refactory.rename(columns = {1630:'Roof'}, inplace = True) ## Flat(1),Arched(0)
   machine_refactory['Material'].replace('0','Block', inplace=True)
   machine_refactory['Material'].replace('1','Brick', inplace=True)
   machine_refactory['Roof'].replace('0',' - Arched Roof', inplace=True)
   machine_refactory['Roof'].replace('1',' - Flat Roof', inplace=True)
   machine_refactory=machine_refactory.astype(str)
   machine_refactory['Refractory (Blocked or Bricked) Cremator']=machine_refactory['Material']+ machine_refactory['Roof']
   machine_refactory=machine_refactory['Refractory (Blocked or Bricked) Cremator']
   machine_refactory.apply(lambda x : x.astype(str)+' '+x.name) #
   print(machine_refactory)

Answer 1

之后

machine_refactory=machine_refactory['Refractory (Blocked or Bricked) Cremator']

machine_refactory是一个系列，所以当你做

machine_refactory.apply(lambda x : x.astype(str)+' '+x.name)

x 在 lambda 中采用单元格值，它们是字符串，因此 x 没有 astype 也没有 name 属性.你想要：

machine_refactory.apply(lambda x: str(x) + machine_refactory.name]
