如何编写一个循环 pro 所有文件 *.py 除了 a.py？

for i in *.py && !(a.py); do 
    python3 $i
done

请问这里有什么问题？我尝试安装https://automatetheboringstuff.com/chapter18/

sudo pip3 install --user python3-xlib
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main'
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 145, in apport_excepthook
    os.O_WRONLY | os.O_CREAT | os.O_EXCL, 0o640), 'wb') as f:
FileNotFoundError: [Errno 2] No such file or directory: '/var/crash/_usr_bin_pip3.0.crash'

Original exception was:
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main'

使用 pip3 安装另一个程序会导致错误：

pip3 install python3-tk
Collecting python3-tk
  ERROR: Could not find a version that satisfies the requirement python3-tk (from versions: none)
ERROR: No matching distribution found for python3-tk
