Consider the following DataFrame:

import pandas as pd
import numpy as np

df = pd.DataFrame({"A":np.arange(5),"B":np.arange(5)})
df
A B
0 0 0
1 1 1
2 2 2
3 3 3
4 4 4

To split this DataFrame into smaller equal-sized DataFrames, use NumPy's array_split(~) method:

np.array_split(df, 3) # list of DataFrames
[ A B
0 0 0
1 1 1,
A B
2 2 2
3 3 3,
A B
4 4 4]
