python - 如何在 Jupyter Notebook 中将字符串格式化程序与 og2ogr 一起使用？

Question

我正在 Jupyter Notebook 中制作一个脚本，它将ogr2ogr在一个循环中执行多个转换。据我所知，我不能直接将变量传递给 ogr2ogr。我可以用字符串格式化程序做到这一点吗？

! ogr2ogr -f "ESRI Shapefile" {fout} "my_orignal_shp.shp".format(fout = "my_output.shp")返回

FAILURE: Unable to open datasource `my_output.shp.format(fout' with the following drivers.

并! (ogr2ogr -f "ESRI Shapefile" {fout} "my_orignal_shp.shp").format(fout = "my_output.shp")返回.format(fout was unexpected at this time.

使用 Windows、Python 3.7、GDAL 3.3.1 和 Jupyter Notebook

更新 我还尝试了以下方法，如GDAL 示例指南中所建议的那样

command = 'ogr2ogr -f "ESRI Shapefile" {i} {o}'
i = r'D:\Documents\my_orignal_shp.shp'
o = r'D:\Documents\my_output.shp'
! os.system(command.format(input=fin, output=fout))

并收到此错误：'os.system' is not recognized as an internal or external command, operable program or batch file.
