Sample datasets in Pandas

Question

When using R it\'s handy to load \"practice\" datasets using

data(iris)

or

data(mtcars)

Is there something s

Answer 1

The builtin pandas testing DataFrame is very convenient.

makeMixedDataFrame():

In [22]: import pandas as pd

In [23]: pd.util.testing.makeMixedDataFrame()
Out[23]:
     A    B     C          D
0  0.0  0.0  foo1 2009-01-01
1  1.0  1.0  foo2 2009-01-02
2  2.0  0.0  foo3 2009-01-05
3  3.0  1.0  foo4 2009-01-06
4  4.0  0.0  foo5 2009-01-07

other testing DataFrame options：

makeDataFrame():

In [24]: pd.util.testing.makeDataFrame().head()
Out[24]:
                   A         B         C         D

makeTimeDataFrame()：

In [28]: pd.util.testing.makeTimeDataFrame().head()
Out[28]:
