# ipynb to py 自動化

## 拿到當前ipynb檔案名稱
### solution
#### get current .ipynb file name
開發環境:VScode

a = globals() 
b = a['__vsc_ipynb_file__']
print(b.split('\\')[-1]) #

每種檔案(.py、.ipynb等)都有隱藏的變數/屬性(像是__main__)。
globals()就像是把ipynb的所有隱藏變數列出來，是一個dict。
當前檔案名稱就在'__vsc_ipynb_file__'的value內，把它拿出來就好了

#### sol:

if __name__ == "__main__":
    def save_to_py():
        dict_env_var = globals()
        key = dict_env_var['__vsc_ipynb_file__']
        current_file_name = key.split('\\')[-1]
        !jupyter nbconvert --to script {current_file_name}

    save_to_py()

[How do I get the current IPython / Jupyter Notebook name](https://stackoverflow.com/questions/12544056/how-do-i-get-the-current-ipython-jupyter-notebook-name)
1. ipynbname 沒屁用 : 跑nb_name = ipynbname.name()跑不會停，github issue也有這個問題，作者沒回
2. ipyparams 沒屁用 : 跑currentNotebook = ipyparams.notebook_name，不會回傳東西，github issue也有這個問題，作者沒回
3. 用javascript語法去跑，還沒試。 [link:Can a jupyter notebook find its own filename?](https://stackoverflow.com/questions/52691468/can-a-jupyter-notebook-find-its-own-filename)
