Error message misformatting

[ENDrain]

Issue

I'm trying to create a virtual environment:

> python -m virtualenv -p="C:/Program Files/Python30/python.exe" venv

The resulting error message has some formatting issues:

RuntimeError: failed to query C:\Program Files\Python30\python.exe with code 1 err: '  File "C:\\Program Files (x86)\\Python39-32\\lib\\site-packages\\virtualenv\\discovery\\py_info.py", line 97\n    self.sysconfig_vars[u"implementation_lower"] = u"python"\n                                              ^\nSyntaxError: invalid syntax\n'

I've learned since creating this that virtualenv does not support 3.0, but this issue is about the error message formatting.

Environment

• OS: Windows_NT x64 10.0.19042
• Python: 3.9.2
• pip list of the host python where virtualenv is installed:
