python - 更改 Python 交互提示 ">>>"

Question

我记得在 Python 3.5 文档中阅读过如何更改 Python 交互式提示上的 >>>，例如调用 help() 将如何更改它到 help>.

但由于某种原因，当我回去尝试内存时，我就是找不到它的说明。有谁知道这是否可能？

你没记错。

它在 sys 中模块(sys.ps1 & sys.ps2):

Strings specifying the primary and secondary prompt of the interpreter. These are only defined if the interpreter is in interactive mode. Their initial values in this case are '>>> ' and '... '. If a non-string object is assigned to either variable, its str() is re-evaluated each time the interpreter prepares to read a new interactive command; this can be used to implement a dynamic prompt.

例如:

   >>> import sys
   >>> sys.ps1 = "3.5>>> "
   3.5>>> sys.ps2 = "3.5... "
   3.5>>>
