quantile

quantitle(self, q=0.5, ...)

q : float or array-like, default 0.5 (50% quantile)

If q is an array, a DataFrame will be returned where the index is q, the columns are the columns of self, and the values are the quantiles.

If q is a float, a Series will be returned where the index is the columns of self and the values are the quantiles.

import pandas as pd
iris = pd.read_csv('iris.csv', sep=',')
df = iris.iloc[:,0:4]
print(df.quantile([0.25,0.50,0.75]))
