I have used lxml extensively in a Pycharm environment that calls on a conda environment.  Lately I encountered an odd error. The correct output of a marylamb.py script goes like this:

<l xmlns="http://www.tei-c.org/ns/1.0"> Mary had a little lamb,</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> Its fleece was white as snow, yeah.</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> Everywhere the child went,</l>

<l xmlns="http://www.tei-c.org/ns/1.0">  The little lamb was sure to go, yeah.</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> He followed her to school one day,</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> And broke the teacher's rule.</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> What a time did they have,</l>

<l xmlns="http://www.tei-c.org/ns/1.0">  That day at school.</l>

<l xmlns="http://www.tei-c.org/ns/1.0"> Tisket, tasket,</l>

<l xmlns="http://www.tei-c.org/ns/1.0">  A green and yellow basket.</l>

<l xmlns="http://www.tei-c.org/ns/1.0">  Sent a letter to my baby,</l>

<l xmlns="http://www.tei-c.org/ns/1.0">   On my way I passed it.</l>

In the buggy output the script runs amok and prints the current line plus the rest of the text. I print it out at the end of this memo. The Pycharms folks were able to identify the conda environment as the likely culprit. If I run the script outside it doeesn’t happen. The problem seems to be limited to lxml running in a conda environment, because scripts that don’t use lxml are not plague by that bug.

Has anybody encountered a similar problem or has a suggestion how to fix it.  I guess not using conda is an option, but it’s convenient in many other ways.  Here is the buggy output, with an empty line added after each line to make it a little more readable
