Checking if dataframe column has unicode-CodePudding

I wonder what is the simplest way to check if a pandas dataframe column has unicode.

I was gonna try df['fieldname'].str.isascii but that does not seem to exist.

CodePudding user response：

In python3, strs are unicode.

Your code, df['fieldname'].str.isascii, returns a Series, which rows of True or False. Since you want to check if the column has at least one str value, you can check as follows:

import pandas as pd

df = pd.DataFrame(
    {
        'text': [1, 2, '3'], # '3' is str here.
    }
)

if True in df['text'].apply(lambda x: x.isascii() if isinstance(x, str) else False).to_list():
    print('at least one ascii')
else:
    print('no ascii')
# at least one str -> this will be printed because '3' is ascii.
