问题 Now I'm working on bioinformatics project for my diploma work. I have written Python-script, which should translate the list of strings of 1000 DNA-Sequences to proteins by 1152 different codontables (genetics codes).

问题 Is there a way to have a timeout when calling IPython.embed() in a python script?
