python3.<x> 和 python3.<x>m 有什么区别

What's the difference between python3.<x> and python3.<x>m

What does the m stand for in python3.6m?

它表示 Python 已配置 --with-pymalloc,它启用了比系统更快的内存分配专用实现 malloc

How does it differ to non m version?

m 版本显然没有配置它。

In which case would I prefer to use python3.6m rather than python3.6?
