__important__（‘ random ’）.randint 导入模块函数只能用一次，from random important randint 是导入对应模块中的函数，两种写法那种性能更高?求大神指点？

1. important -> import
2. from random import randint 等价于 randint = __import__('random').randint 3.你可以理解为性能没区别 4.Python 比较 CPU 性能没什么太大意义，高并发下 io 性能才是需要考虑的。 |

important ……
楼主建议还是先学一下英语，别在性能高低这种有的没的问题上浪费时间 |
