import pandas as pd
d = {'one' : pd.Series([1., 2., 3.], index = ['a', 'b', 'c']), 'two' : pd.Series([1., 2., 3., 4.], index = ['a', 'b', 'c', 'd'])}
df = pd.DataFrame(d)
df1 = pd.DataFrame(d, index = ['d', 'b', 'a'])
df2 = pd.DataFrame(d, index = ['d', 'a'], columns = ['two', 'three'])
print(df.iloc[0:2])
print(df1.iloc[0:2])
print(df2.iloc[0:2])Output
one two
a 1.0 1.0
b 2.0 2.0
one two
d NaN 4.0
b 2.0 2.0
two three
d 4.0 NaN
a 1.0 NaN
