deep copy of StyleFrame object

How can I make a shallow or deep copy of StyleFrame object? When I use copy.copy(sf) or , copy.deepcopy(sf) I get error: "RecursionError: maximum recursion depth exceeded while calling a Python object"

import copy
from StyleFrame import StyleFrame
import pandas as pd
df=pd.DataFrame([list('abc')])
sf=StyleFrame(df)
copy.copy(sf)

Solution

  • Just pass the original StyleFrame object to StyleFrame. Internally it will deep copy the underlying dataframe and will also copy some internal attributes.

    sf = StyleFrame({'a': [1, 2]})
print(id(sf))
new_sf = StyleFrame(sf)
print(id(new_sf))
