Translator from Python into C (русская версия)

Use Python-syntax to write a clear C-code for your microcontrollers:

About another variants of Python to C translating

Examples

Using is really simple with shortcuts:

from py2c.shortcuts import trans_c

my_python_code = '''
    def hello(a: int, b: int = 5) -> string:
        return 'good' if a + b > 0 else 'not good'
'''

c_code = trans_c(my_python_code)
print(c_code)

Without shortcuts if you want more control:

from py2c.bytecode_walker import translate
from py2c.translator_cpp import TranslatorC

my_python_code = '''
    def hello(a: int, b: int = 5) -> string:
        return 'good' if a + b > 0 else 'not good'
'''

with open('c_code.c') as c_file:
    translator = TranslatorC(save_to=c_file)
    translate(translator, my_python_code)

Install/Uninstall

Use this command to install Py2C:

pip install git+https://github.com/syeysk/sy_py2c.git

Use this command to uninstall Py2C:

pip uninstall py2c

Function's and class' description

py2c.shortcuts.trans_c(source_code, write_to=None) - translate a python-code into c-code. Arguments:

• source_code - a source python-code like unicode string (type of str) or text file object (returning open function)
• write_to - a file object to write a result c-code. If write_to is None (as default), the function will return the c-code as string (type of str)

py2c.TranslatorC(save_to) - class of python-to-c translator. Contains some methods to translate constructions. Arguments:

• save_to - a file object to write the result c-code

py2c.translate(translator, source_code: str) - convert source_code into AST, walk it and build c-code. Arguments:

• translator - a instance of translator. For example, py2c.TranslatorC or py2c.TranslatorCpp
• source_code - a source python-code (type of str)

Command line interface examples

You can use py2c or python -m py2c equivalently.

Create your_source_code.c with c-code:

py2c your_source_code.py

Create your_output_code.c with c-code:

py2c your_source_code.py -o your_output_code.c

Print c-code into console:

py2c your_source_code.py -p
