Changing Column dtypes in DataFrame

[Scott]

Hi everyone,

I have a DF with roughly 700 columns. I'd like to create a loop which loops through columns updating dtype category columns to object columns.I have created this loop but is giving me an error. Can anyone help?

for col in df.columns:
    col_type = df[col].dtype
    
    if col_type = category:
        df[col] = df[col].astype('object')

Thanks
