如何为 pandas 数据库中的特定行和列分配值？

Question

I have an integer:

num = 1

,and a database table points :

   X   Y
0
1
2
3

How would I go about placing num into column X and field 3 using pandas?

I have searched around and found points.ix[] , which selects a specific row but using this I get an error message:

AttributeError: 'DataFrame' object has no attribute 'ix'

Apart from this I can't find anything else.

Answer 1

you can also try, df.iat[3,0]

Thanks

Answer 2

pandas.DataFrame.ix deprecated since version 0.20.0

You can use df.loc[3, 'X'] for the same result.
