Since movies is a list of dictionaries (which are unhashable), converting it to a set to get rid of duplicates will not work. Instead you have to iterate and append each movie to the movies list on the condition that it does not already exist there. You have already tried to do this with the if statement inside the for loop. The problem is that your if statement is always True because your are checking just for a Title and not for the whole dictionary object. You can fix it like this:

The whole point of the musl-gcc wrapper script is to invoke gcc with the include and library paths adjusted to isolate it from the host include and library ecosystem (which are assumed to be glibc-based). That includes the kernel headers for your host system. If you want to use any libraries (including "header-only libraries" like the kernel headers) with musl-gcc, you need to build a version against musl instead of glibc and install it in the musl include/library path.

For kernel headers, they don't actually depend on the libc or have any library files; it's just the headers. So you can probably get by with copying (or symlinking) the linux, asm, and asm-generic directories from /usr/include to the musl include dir. Alternatively you can install them from kernel sources.

If you find you need any significant amount of third-party library stuff, though, it makes more sense to just drop musl-gcc and use a real cross-compiler. You can get prebuilt binary ones if you're willing to trust them from musl.cc, or build your own (takes about 15 minutes on a typical system nowadays) with musl-cross-make. This will give you kernel headers automatically, as well as a full set of GCC target libraries that let you build C++ software, OpenMP-using software, etc.
