Hash each value in a pandas data frame

Question

In python, I am trying to find the quickest to hash each value in a pandas data frame.

I know any string can be hashed using:

hash('a string')

But how do I apply this function on each element of a pandas data frame?

This may be a very simple thing to do, but I have just started using python.

Answer 1

Pandas also has a function to apply a hash function on an array or column:

import pandas as pd

df = pd.DataFrame({'a':['asds','asdds','asdsadsdas']})
df["hash"] = pd.util.hash_array(df["a"].to_numpy())
