How can I ignore ValueError when I try to remove an element from a list?

Question

How can I ignore the \"not in list\" error message if I call a.remove(x) when x is not present in list a?

This is my situation:

Answer 1

A better way to do this would be

source_list = list(filter(lambda x: x != element_to_remove,source_list))

Because in a more complex program, the exception of ValueError could also be raised for something else and a few answers here just pass it, thus discarding it while creating more possible problems down the line.
