Python pandas slice dataframe by multiple index ranges

You can use numpy’s r_ “slicing trick”:

df = pd.DataFrame({'a':range(10,100)})
df.iloc[[10:12, 25:28]]

NOTE: this now gives a warning The module is deprecated and will be removed from pandas in a future version. Import numpy directly instead. To do that, you can import numpy as np and then slice the following way:

df.iloc[np.r_[10:12, 25:28]]

This gives:

10  20
11  21
25  35
26  36
27  37
