# GIL Talk
[](https://github.com/aktech/gil_talk/actions/workflows/test.yml)
A talk on Global Interpreter lock.
## Contents
### Functions threads API
```bash
$ python python_multithreading/function_threads.py
```
### Class based threads API
```bash
$ python python_multithreading/class_threads.py
```
### Extension Module
Python C extension module is written in `extension_module.c` to build it on mac, run:
```bash
$ python python_c_extension/setup.py build
```
The above will will compile `extension_module.c`, and produce an extension module
in the build directory. Depending on the system, the module file will end up in
a subdirectory `build/lib.system.extension_module.so`.
Copy the built `*.so` file in the current directory, for e.g.:
```bash
$ cp -r build/*/* python_c_extension
```
The function defined in extensions module is used in `c_ext_gil_test.py`, run it
as following:
```bash
$ python python_c_extension/c_extension_gil.py
Single Thread: 2.118302
Two Threads: 1.348021
```
### Compile and run C Threads
* compile
```bash
$ g++ cpp_multithreading/c_threads.cpp -o cpp_multithreading/c_threads
```
* run
```bash
$ ./cpp_multithreading/c_threads
```
