py_compile — Compile Python source files
The py_compile module provides a function to generate a byte-code file
from a source file, and another function used when the module source file is
invoked as a script.
Though not often needed, this function can be useful when installing modules for
shared use, especially if some of the users may not have permission to write the
byte-code cache files in the directory containing the source code.
- Exception raised when an error occurs while attempting to compile the file.
py_compile.compile(file[, cfile[, dfile[, doraise]]])
- Compile a source file to byte-code and write out the byte-code cache file. The
source code is loaded from the file name file. The byte-code is written to
cfile, which defaults to file + 'c' ('o' if optimization is
enabled in the current interpreter). If dfile is specified, it is used as the
name of the source file in error messages instead of file. If doraise is
true, a PyCompileError is raised when an error is encountered while
compiling file. If doraise is false (the default), an error string is
written to sys.stderr, but no exception is raised.
- Compile several source files. The files named in args (or on the command
line, if args is not specified) are compiled and the resulting bytecode is
cached in the normal manner. This function does not search a directory
structure to locate source files; it only compiles files named explicitly.
When this module is run as a script, the main() is used to compile all the
files named on the command line. The exit status is nonzero if one of the files
could not be compiled.
