Python Py_compile Module
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.
Importing the Module
import py_compileCompiling a File
The py_compile.compile() function compiles a source file to byte-code and writes out the byte-code cache file.
Basic Usage
import py_compile
# Compile a file named 'myscript.py'
# This will create a .pyc file in the __pycache__ directory
py_compile.compile('myscript.py')Specifying Output File
You can specify the name of the byte-code file using the cfile argument.
import py_compile
py_compile.compile('myscript.py', cfile='myscript.pyc')Error Handling
By default, compile() does not raise an exception if compilation fails (it prints to stderr). To raise an exception, set doraise=True.
import py_compile
try:
py_compile.compile('broken_script.py', doraise=True)
except py_compile.PyCompileError as e:
print(f"Compilation failed: {e}")Command Line Usage
You can also use this module as a script to compile several source files.
python -m py_compile file1.py file2.py
