I know this thread is a bit old, but it took me some time to get to the heart of this, so I wanted to share.
In my project, I had the main script in a parent directory, and, to differentiate the modules, I put all the supporting modules in a sub-folder called "modules". In my main script, I import these modules like this (for a module called report.py):
from modules.report import report, reportErrorIf I call my main script, this works. HOWEVER, I wanted to test each module by including a main() in each, and calling each directly, as:
python modules/report.pyNow Python complains that it can't find "a module called modules". The key here is that, by default, Python includes the folder of the script in its search path, BUT NOT THE CWD. So what this error says, really, is "I can't find a modules subfolder". The is because there is no "modules" subdirectory from the directory where the report.py module resides.
I find that the neatest solution to this is to append the CWD in Python search path by including this at the top:
import sys sys.path.append(".")Now Python searches the CWD (current directory), finds the "modules" sub-folder, and all is well.

Syntax
Values
<clip-source>
A url() referencing an SVG <clipPath> element.
<basic-shape>A shape whose size and position is defined by the <geometry-box> value. If no geometry box is specified, the border-box will be used as the reference box. One of:
inset()Defines an inset rectangle.
circle()Defines a circle using a radius and a position.
ellipse()Defines an ellipse using two radii and a position.
polygon()Defines a polygon using an SVG filling rule and a set of vertices.
path()Defines a shape using an optional SVG filling rule and an SVG path definition.
<geometry-box>If specified in combination with a <basic-shape>, this value defines the reference box for the basic shape. If specified by itself, it causes the edges of the specified box, including any corner shaping (such as a border-radius), to be the clipping path. The geometry box can be one of the following values:
margin-boxUses the margin box as the reference box.
border-boxUses the border box as the reference box.
padding-boxUses the padding box as the reference box.
Uses the content box as the reference box.
fill-boxUses the object bounding box as the reference box.
stroke-boxUses the stroke bounding box as the reference box.
view-boxUses the nearest SVG viewport as the reference box. If a viewBox attribute is specified for the element creating the SVG viewport, the reference box is positioned at the origin of the coordinate system established by the viewBox attribute and the dimension of the size of the reference box is set to the width and height values of the viewBox attribute.
noneNo clipping path is created.
Note: A computed value other than none results in the creation of a new stacking context the same way that CSS opacity does for values other than 1.
