* pycontainers: Properly handle KeyErrorsSylvain Munaut2020-03-041-5/+11
| | | | | | | | | | | | | We raise a C++ exception to abort the rest of the execution of the function. At the same time we standardize on using a throw runtime error as the method to avoid warning when not returning values. (some places used this throw and some other used std::terminate) Fixes #403 Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
