Python supports running .zip'd .py files:
$ cat
__main__.py
#!/usr/bin/python3
print("Hello World")
$ zip pyzip.zip __main__.py
$ head −1 __main__.py | cat − pyzip.zip >
pyzip
$ chmod a+x pyzip
They require special handling to not mangle the shebang.
Unclear, as many tools can, after all, generate these .zip files.
