↑↑↑以上为测试代码↑↑↑

源码路径为D:\TestCode\testPath.py

exe文件路径为D:\TestCode\dist\testPath.exe

结果

0x00

命令行进入源码目录下运行

命令：

D:\TestCode>python testPath.py

结果：

testPath.py
D:\TestCode\testPath.py
using sys.executable: 'C:\\Users\\LQT\\AppData\\Local\\Programs\\Python\\Python37'
using sys.argv[0]: 'D:\\TestCode'
testPath.py
D:\TestCode
D:\TestCode

0x01

命令行进入非源码目录下运行

命令：

E:\>python D:\TestCode\testPath.py

结果：

D:\TestCode\testPath.py
D:\TestCode\testPath.py
using sys.executable: 'C:\\Users\\LQT\\AppData\\Local\\Programs\\Python\\Python37'
using sys.argv[0]: 'D:\\TestCode'

使用pyinstaller打包成单个exe文件之后，使用命令行进入exe所在目录下运行

命令：

D:\TestCode\dist>testPath.exe

结果：

testPath.py
D:\TestCode\dist\testPath.py
using sys.executable: 'D:\\TestCode\\dist'
using sys.argv[0]: 'D:\\TestCode\\dist'
testPath.exe
C:\Users\LQT\AppData\Local\Temp\_MEI413842\base_library.zip
D:\TestCode\dist

使用pyinstaller打包成单个exe文件之后，使用命令行在非exe所以目录下运行

命令：

E:\>D:\TestCode\dist\testPath.exe

结果：

testPath.py
E:\testPath.py
using sys.executable: 'D:\\TestCode\\dist'
using sys.argv[0]: 'D:\\TestCode\\dist'
D:\TestCode\dist\testPath.exe

0x04

直接双击运行exe文件

结果：

testPath.py
D:\TestCode\dist\testPath.py
using sys.executable: 'D:\\TestCode\\dist'
using sys.argv[0]: 'D:\\TestCode\\dist'
D:\TestCode\dist\testPath.exe
C:\Users\LQT\AppData\Local\Temp\_MEI484282\base_library.zip
D:\TestCode\dist

结论

print('using sys.argv[0]:', repr(os.path.dirname(os.path.realpath(sys.argv[0]))))

以上代码可正确获取当前目录。
