Error 000354 in create a new feature class?

[SiqiHuang1]

Hi!

I am working with ArcGIS Pro. I am trying to use an insert cursor to create a new polyline feature from a list of coordinates in pythonWin. Here is what my code is. Could anyone tell me what am I doing wrong or missing?

Thank you!

code formatting should be used

If you are creating a featureclass, you need to specify *.shp if a shapefile is required and its destination is a folder, otherwise, you need to specify a geodatabase location.

Also, you need to "raw encode" you paths if using a single backslash

eg... r"C:\YourFolderPath\AnotherFolder\A_geodatabase.gdb"
