问题
I'm trying to install and use PyQt5 on my Windows 10 computer. Actually, it's already installed but IDLE does not recognize the package.
I tried to import PyQt5 after I installed it but I got an import error. Then I tried something else:
pip install pyqt5
Here, I got a syntax error. Does anybody have an idea what's the problem? Thanks in advance.
