使用列表定义的列名初始化 Pandas 数据框

Question

I want to initilise a pandas dataframe with 1613 rows. I want to define the column names by the list 'indicns_list' (which has 471 elements). I tried this:

con_meds3 = pd.DataFrame(np.nan, index=range(0,1613),columns=indicns_list)

But I'm getting this error:

ValueError: Shape of passed values is (1613, 471), indices imply (1613, 1)

help! :)

Answer 1

their is issue in the indicns_list if below code does fine. try this

con_meds3 = pd.DataFrame(np.nan, index=range(0,1613),columns=[i for i in range(1613)])
