TypeError: randint() takes exactly 3 arguments (4 given)

Question

What's wrong here?

import pandas as pd
import numpy as np
ts = pd.Series(randint(0, 500, len(rng)), index=rng)

Gives: TypeError: randint() takes exactly 3 arguments (4 given)

System: Python 2.7.5+ Pandas 0.12.0-2ubuntu1

Answer 1

Seems you randint comes from the standard library (random.randint)

Here are two ways to correct your code

1. modify randint to np.random.randint

2. add from numpy.random import randint
