Check, infer, or change your DataFrame’s column data types.

• df.astype() → Convert the dtype of one or more columns to a specified type.
• df.convert_dtypes() → Convert columns to best possible dtypes automatically.
• df.infer_objects() → Infer better dtypes for object columns.
• df.copy() → Create a deep or shallow copy to avoid modifying original data.
• df.set_flags() → Set internal metadata flags.
• df.flags → Inspect DataFrame’s flags (rarely used).
• df.attrs → Same as above; user-defined metadata for extra context.
