In short: words are delimited by spaces, as long as those spaces are not escaped by a backslash, or inside a quoted string. Single and double quotes are equivalent, and the quote characters can be backslash-escaped. The backslash is stripped from any two-character escape sequence, leaving only the escaped character. The quote characters are stripped from any quoted string. Returns a list of words.

'py_files' is a list of files to compile; any files that don't end in ".py" are silently skipped. 'optimize' must be one of the following: 0 - don't optimize 1 - normal optimization (like "python -O") 2 - extra optimization (like "python -OO") If 'force' is true, all files are recompiled regardless of timestamps. The source filename encoded in each bytecode file defaults to the filenames listed in 'py_files'; you can modify these with 'prefix' and 'basedir'. 'prefix' is a string that will be stripped off of each source filename, and 'base_dir' is a directory name that will be prepended (after 'prefix' is stripped). You can supply either or both (or neither) of 'prefix' and 'base_dir', as you wish. If 'dry_run' is true, doesn't actually do anything that would affect the filesystem. Byte-compilation is either done directly in this interpreter process with the standard py_compile module, or indirectly by writing a temporary script and executing it. Normally, you should let 'byte_compile()' figure out to use direct compilation or not (see the source for details). The 'direct' flag is used by the script generated in indirect mode; unless you know what you're doing, leave it set to None. zbyte-compiling is disabled.Nr)mkstempz.py)mktempz$writing byte-compilation script '%s'wz2from distutils.util import byte_compile files = [ z, z] z byte_compile(files, optimize=z, force=z, prefix=z , base_dir=z, verbose=z$, dry_run=0, direct=1) )rz removing %s)rr7) optimizationzinvalid prefix: filename z doesn't start with zbyte-compiling %s to %sz%skipping byte-compilation of %s to %s)#rdont_write_bytecodertempfilerrfrrrrfdopenopenwriterSmaprepr executableextend subprocess"_optim_args_from_interpreter_flagsrrrrP py_compiler importlibutilcache_from_sourcerrOrRbasenamerdebug)py_filesoptimizeforcerbase_dirrrdirectr script_fd script_namerscriptcmdrfileoptcfiledfile cfile_bases r" byte_compilerdshP '(EFF~'1}  ; ('.u~ $Y 7E$9c2k3/ " UZZD((;=;+FPWX 'DBCyE! 1}$Mbx!88C8P!88>E #f+&&0$)c&km, Xu5))%0JE$.HH6jI"eU3IIEtZXAk ; ''+VE] Y ;sJ7A$J"JJ"J,cJ|jd}d}|j|S)zReturn a version of the string escaped for inclusion in an RFC-822 header, by ensuring there are 8 spaces space after each newline.  z )rGrS)headerlinesrNs r" rfc822_escapers% LL E C 88E?r$)zerror: )Nrr)rrNNrrN)+__doc__importlib.utilrrrrrrr functoolserrorsrr _modifiedrr_logrr#rplatformr3r:r5r<rDr@rVr^ lru_cacherhryrtrrrrrrrrrrr4r$r"rs   E$: <<8/ @*  :N*,,,4&(+/. .
