AttributeError: 'Series' object has no attribute 'iterrows' - Python

问题

Below is my code. I do not understand why it has error: AttributeError: 'Series' object has no attribute 'iterrows'.

Could someone advise me on a way to correct it?

  1. a = pd.DataFrame(index=['D1', 'D2', 'D3', 'D4'], columns=[x for x in range(0, 10)])
  2. a.loc[:] = 5
  3. for index, row in a.loc['D1', :].iterrows():
  4.     for col in a.columns:
  5.         if a.at[index, col] > 0:
  6.             print(True)

  1. a=pd.DataFrame(index=['D1','D2','D3','D4'], columns=[x for x in range(0,10)])
  2. a.loc[:]=5
  3. for index,row in a.loc['D1',].iterrows():
  4.     for col in a.columns:
  5.       if a.at[index,col]>0:

使用数据框架本身，而不是单独的行：

  1. a=pd.DataFrame(index=['D1','D2','D3','D4'], columns=[x for x in range(0,10)])
  2. a.loc[:]=5
  3. for index,row in a.iterrows():
  4.     for col in a.columns:
  5.         if a.at[index,col]>0:
  6.             print(True)
英文:

Use the dataframe as such, not a single row:

  1. a=pd.DataFrame(index=['D1','D2','D3','D4'], columns=[x for x in range(0,10)])
  2. a.loc[:]=5
  3. for index,row in a.iterrows():
  4.     for col in a.columns:
  5.       if a.at[index,col]>0:
  6.         print(True)
