how to format column in currency in python

locale.setlocale(locale.LC_ALL, 'pt_BR.UTF-8') 

filtered_data['Receita Total'] = filtered_data['Receita Total'].apply(lambda x: locale.currency(x, grouping=True))

filtered_data['Margem Final'] = filtered_data['Margem Final'].apply(lambda x: f"{x:.2f}%")

How can I format my columns as currency without them ending up in object/string format? I want them to be numeric so that I can sort the numbers from highest to lowest without them being in alphabetical order.

My table has this format

print(filtered_data.dtypes)
row.names         object
data              object
ano              float64
razaoSocial       object
cnpj              object
entidadeId        object
status_final      object
total_exames       int64
receita_total    float64
margem_final     float64

When I format the column it changes to object, but I don't want that to happen

filtered_data['receita_total'] = filtered_data['receita_total'].apply(lambda x: locale.currency(x, grouping=True))

filtered_data['margem_final'] = filtered_data['margem_final'].apply(lambda x: f"{x:.2f}%")

print(filtered_data.dtypes)
row.names         object
data              object
ano              float64
razaoSocial       object
cnpj              object
entidadeId        object
status_final      object
total_exames       int64
receita_total     object
margem_final      object
dtype: object
