From the DataFrames created in previous question, write code to display only rows 0 and 1 from DataFrames df, df1, and df2.

Solution
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
