在 Python 输入中使用向上箭头获取先前的输入

Question

Problem:

Previously I wrote all of my python code on a Windows 10 machine, but more recently I've been trying to move over to MacOS. Everything is working just fine, with one exception. I'm writing a program that uses the python 'input' function and when pressing ↑ on MacOS it prints '^[[a' but on Windows 10 it prints the previous input. Is there get the previous input with the up arrow on Mac?

---

Example Code:

while True:
   string = input()
   print(string)

On Windows hitting ↑ will print the previous input but on Mac '^[[a' will print

Use readline module to provide reading and writing of history files. More info on that in the docs

import readline

while True:
   string = input()
   print(string)
