如何读取 dataframe 上所有未命名的列？

Question

I have dataframe value data like this

    acolumn     bcolumn
70  0.503462    0.6
71  0.480712    0.5
72  0.505440    0.5
73  0.553907    0.5
74  0.344214    0.5

How to read the first unnamed column at dataframe? I already tried using iloc(), columns[0] and still the output is acolumn, I want the output is like this

70, 71, 72, 73, 74

I want to use that data to labelling my graph at my website.

Answer 1

I think what you want is the index of the dataframe.

Try:

df.index
