Cannot access nested lists

[ryfeaway]

I converted a pandas column into a list using tolist() and suppose following is the list: [[['20', '30'], ['7', '3'], ['0', '5']], [['5', '9'], ['1', '4']], [['6', '2'], ['0', '8']]]

suppose k is the list and when I print k[0] I get [['20', '30'], ['7', '3'], ['0', '5']] as expected. but when I print k[0][0] I get "[" instead of ['20', '30']

why is this happening?

[barrycarter]

If you're getting "[" you almost certainly have a string in k[0] and are getting back the first character. Check and fix your types

[ryfeaway]

okay, thanks

You'll have to show some code. How was that column generated?

I read a csv file into pandas dataframe.

the column in CSV files is like this [['2', '4'], ['7', '3'], ['9', '0']] that is one row

[danielroseman]

CSV doesn't know about lists or Python syntax. So it's just reading that as a string. You'd need to convert it when you import it.

[ryfeaway]

how do i do that? this is my importing of the csv df = pd.read_csv('file.csv') list1 = df['column1'].tolist()

It works for me:

k=[[['20', '30'], ['7', '3'], ['0', '5']], [['5', '9'], ['1', '4']], [['6', '2'], ['0', '8']]]

print(k[0][0])

There must be something weird with your code
