Python做个界面小工具这么简单，你确定不学一下！

1)、创建目录
mkdir myProjectfile （linux、window通用，当然也可以手动建一个文件夹命名）
2）进入目录
cd myProjectfile （也可以直接打开建立的文件夹路径cmd命令进入）
3）配置虚拟环境路径
linux： export PIPENV_VENV_IN_PROJECT=1
window： set PIPENV_VENV_IN_PROJECT=1 (注意项目不能在C盘，如果此处没有设置，默认虚拟环境路径在C盘下)
4）创建虚拟环境
pipenv install 
5）激化环境
pipenv shell
6）安装需要的包
pipenv install PyQt5/pyqt5-tools/pywin32/PyPDF2

pyuic5 -o ui_mainWindow.py  mainWindow.ui
pyuic5 -o ui_transformWindow.py  transformWindow.ui

def all_path(dirname):
    result = []
    for maindir, subdir, file_name_list in os.walk(dirname):
        for filename in file_name_list:
            apath = os.path.join(maindir, filename)
            result.append(apath)
    return result

def GetExtNamesList(fileslist,ext):
    filenames=[]
    for file in fileslist:
        fileinfo=os.path.splitext(file)
        if fileinfo[1]==ext:
            filenames.append(file)
    return filenames
