crowsetta.formats.bbox.audbbox.df_to_lines

crowsetta.formats.bbox.audbbox.df_to_lines(df: DataFrame) → list[str]

Convert a pandas.DataFrame to a list of str that can be saved as a txt file in Audacity extended label track format.

This function is (roughly) the inverse of crowsetta.formats.bbox.audbbox.txt_to_records().

Parameters:

df (pandas.DataFrame) – With contents of a txt file in Audacity extended label track format, after being loaded and parsed by crowsetta.formats.bbox.audbbox.audbbox_txt_to_df()

Returns:

lines – List of strings that can be saved to a text file by calling writelines().

Return type:

list

Notes

We work with Audacity txt files this way, instead of munging and then calling pandas.DataFrame.to_csv(), so that we can be sure that we can round-trip data without corrupting it.
