"The previous chapters discussed how to extend Python, that is, how to extend "
"the functionality of Python by attaching a library of C functions to it. It "
"is also possible to do it the other way around: enrich your C/C++ "
"application by embedding Python in it. Embedding provides your application "
"with the ability to implement some of the functionality of your application "
"in Python rather than C or C++. This can be used for many purposes; one "
"example would be to allow users to tailor the application to their needs by "
"writing some scripts in Python. You can also use it yourself if some of the "
"functionality can be written in Python more easily."

"Os capítulos anteriores discutiram como estender o Python, ou seja, como "
"expandir a funcionalidade do Python anexando uma biblioteca de funções em C "
"a ele. Também é possível fazer o inverso: enriquecer sua aplicação em C/C++ "
"incorporando o Python nela. A incorporação fornece à sua aplicação a "
"capacidade de implementar parte da funcionalidade da aplicação em Python em "
"vez de C ou C++. Isso pode ser usado para diversos propósitos; um exemplo "
"seria permitir que os usuários personalizem a aplicação de acordo com suas "
"necessidades escrevendo alguns scripts em Python. Você também pode usá-la se "
"parte da funcionalidade puder ser escrita em Python mais facilmente."

"Embedding Python is similar to extending it, but not quite. The difference "
"is that when you extend Python, the main program of the application is still "
"the Python interpreter, while if you embed Python, the main program may have "
"nothing to do with Python --- instead, some parts of the application "
"occasionally call the Python interpreter to run some Python code."
msgstr ""
"Incorporar o Python é semelhante a estendê-lo, mas não exatamente. A "
"diferença é que, ao estender o Python, o programa principal da aplicação "
"ainda é o interpretador Python, enquanto que, se você incorporar o Python, o "
"programa principal pode não ter nada a ver com o Python — em vez disso, "
"algumas partes da aplicação chamam ocasionalmente o interpretador Python "

"So if you are embedding Python, you are providing your own main program. "
"One of the things this main program has to do is initialize the Python "
"interpreter. At the very least, you have to call the function :c:func:"
"`Py_Initialize`. There are optional calls to pass command line arguments to "
"Python. Then later you can call the interpreter from any part of the "
"application."

"There are several different ways to call the interpreter: you can pass a "
"string containing Python statements to :c:func:`PyRun_SimpleString`, or you "
"can pass a stdio file pointer and a file name (for identification in error "
"messages only) to :c:func:`PyRun_SimpleFile`. You can also call the lower-"

"The simplest form of embedding Python is the use of the very high level "

"needing to interact with the application directly. This can for example be "
"used to perform some operation on a file. ::"

#: ../../extending/embedding.rst:78
msgid ""
"The :c:func:`Py_SetProgramName` function should be called before :c:func:"
"`Py_Initialize` to inform the interpreter about paths to Python run-time "
"libraries. Next, the Python interpreter is initialized with :c:func:"
"`Py_Initialize`, followed by the execution of a hard-coded Python script "
"that prints the date and time. Afterwards, the :c:func:`Py_FinalizeEx` call "
"shuts the interpreter down, followed by the end of the program. In a real "
"program, you may want to get the Python script from another source, perhaps "
"a text-editor routine, a file, or a database. Getting the Python code from "
"a file can better be done by using the :c:func:`PyRun_SimpleFile` function, "
"which saves you the trouble of allocating memory space and loading the file "
"contents."
