将循环结果添加为数据帧中的行

由 发布于

I am trying to make this for loop print the results as respective rows of the same dataframe. I tried this code but it doesn't seem to be working. It is giving an index error right now because it outputs separate empty dataframes for each iteration.

list2=[(('ATM',), ('ROA',)), (('ATM',), ('ROE',)), (('ATM',), ('NIM',)), (('ATM',), ('ROA', 'ROE'))]
tm_final = {0: 3, 1: 6, 2: 4, 3: 2, 4: 0}
totalrows=sum(tm_final[i]>0 for i in tm_final)
df=pd.DataFrame(columns=['A','B','C'])
for i in tm_final:
  if tm_final[i]>0:
    for j in range(totalrows):
      df.iloc[j,0]=i
      df.iloc[j,1]=str(list2[i])
      df.iloc[j,2]=tm_final[i]
    print(df)

所需结果：

   A                B                             C
   0  (('ATM',), ('ROA',))                        3
   1  (('ATM',), ('ROE',))                        6
   2  (('ATM',), ('NIM',))                        4
   3  (('ATM',), ('ROA', 'ROE'))                  2
