finding a row index and column index value in Pandas

Question

I want to find a index of row, by giving definite column number.

import pandas as pd
list1=[['a1','a2','a3'],['b1','b2','b3'],['c1','c2','c3']]
df = pd.DataFrame(list1)

how can I find it?

Answer 1

To get it, you have to use iloc in the following way:

print(df.iloc[1][1])

Answer 2

You can use the.iloc attribute. Below is an example:

  df.iloc[1,2]

This gets the object at row 1 and column 2.

You can even splice using a colon. Example:

  df.iloc[2:5 , 3:8]

This gets all the elements from rows 2 to 5 and 3 to 8.

More information on iloc can be found here:
