I have been using Python to perform gdal_warp commands like so:

options = f"-te {extent} -tr {pixelsize}"
interpolated_tif = gdal.Warp('c:/users/public/warped.tiff', 'c:/users/public/input.tif', options=options)

However, now I need to perform gdal_calc and gdal_edit commands in Python but there doesn't seem to be a gdal.Calc or gdal.Edit - how can I perform these commands then?

from osgeo_utils import gdal_calc
ds = gdal_calc.Calc()

The function takes the following arguments:

calc: MaybeSequence[str],
outfile: PathLikeOrStr | None = None,
NoDataValue: Number | None = None,
type: GDALDataType | str | None = None,
format: str | None = None,
creation_options: Sequence[str] | None = None,
allBands: str = "",
overwrite: bool = False,
hideNoData: bool = False,
projectionCheck: bool = False,
color_table: ColorTableLike | None = None,
extent: Extent | None = None,
projwin: Tuple | GeoRectangle | None = None,
user_namespace: Dict | None = None,
debug: bool = False,
quiet: bool = False,
progress_callback: Any = gdal.TermProgress_nocb,
**input_files: Any

Some examples from the docstring:

add two files together:
    Calc("A+B", A="input1.tif", B="input2.tif", outfile="result.tif")

average of two layers:
    Calc(calc="(A+B)/2", A="input1.tif", B="input2.tif", outfile="result.tif")

set values of zero and below to null:
    Calc(calc="A*(A>0)", A="input.tif", A_band=2, outfile="result.tif", NoDataValue=0)

work with two bands:
    Calc(["(A+B)/2", "A*(A>0)"], A="input.tif", A_band=1, B="input.tif", B_band=2, outfile="result.tif", NoDataValue=0)

sum all files with hidden noDataValue
    Calc(calc="sum(a,axis=0)", a=['0.tif','1.tif','2.tif'], outfile="sum.tif", hideNoData=True)
