How are iloc and loc different in Python Pandas?

PandasServer Side ProgrammingProgramming

Let's take an example to understand the difference between iloc and loc. Basically loc[0] returns the value present at 0 index, whereas iloc[0] returns the value present at the first location of a series.

Steps

  • Create a one-dimensional ndarray with axis labels (including time series).

  • Print the input series.

  • Use loc[0] to print the value present at 0th index.

  • Use iloc[0] to print the value present at the first location of the series table.

Example

 Live Demo

import pandas as pd
s = pd.Series(list("AEIOU"), index=[2, 1, 0, 5, 8])
print "Input series is:\n", s
print "Value at index=0:", s.loc[0]
print "Value at the 1st location of the series:", s.iloc[0]

Output

Input series is:
2  A
1  E
0  I
5  O
8  U
dtype: object
Value at index=0: I
Value at the 1st location of the series: A
