how to use df.iloc and loc code example

Example 1: loc and iloc in pandas

iloc slicing gives all the data upto the position that is passed as argument
loc gives all the data upto the label that is passed as argument
n = pd.Series([1,2,3,4],index = [0,1,2,3])
print("With iloc we got")
print(n.iloc[:2])
print("With loc we got")
print(n.loc[:2])


With iloc we got
0    1
1    2
dtype: int64
With loc we got
0    1
1    2
2    3
