Python如何拨打2to3?

[英]How to call 2to3 in Python?

Is there a way I could convert a python2 string to a python3 string by calling 2to3 in python without having to call it via command line?有没有一种方法可以通过在 python 中调用2to3将 python2 字符串转换为 python3 字符串,而无需通过命令行调用它?

input = 'a=raw_input()'
output = 'a=input()'

2to3 is open source: 2to3是开源的:
