It's an assignment operator shorthand for /and =.
它是/and的赋值运算符简写=。
Example:
例子：
x = 12
x /= 3
# equivalent to
x = x / 3
If you use help('/='), you can get the full amount of symbols supported by this style of syntax (including but not limited to +=, -=, and *=), which I would strongly encourage.
如果你使用help('/=')，你可以得到全额通过这种风格语法的支持符号（包括但不限于+=，-=和*=），我强烈鼓励。

It's an augmented assignment operator for floating point division. It's equivalent to
它是浮点除法的增强赋值运算符。它相当于
x = x / 3
