python - 我要导入什么 : file_name or class in Python?

Question

我有一个名为 schedule.py 的文件:

class SchedGen:
    """ Class creates a pseudo random Schedule. 
    With 3/4 of total credit point required for graduation"""
    def __init__(self, nof_courses=40):
        random.seed()
        self.courses = {}
        self.nof_courses = nof_courses

        for i in xrange(nof_courses):
            self.courses[i] = college.Course(i)

        self.set_rand_cred()
        self.set_rand_chance()
        self.set_rand_preq_courses()



    def set_rand_cred(self):
        """ Set random credit to courses uniformly between 2 and 6"""
        temp_dict = self.courses.copy()

在导入日程表内容时，我会像这样import schedule:

import schedule

如果那是正确的，我如何从 SchedGen 类访问函数 set_rand_cred(self)？

Answer 1

你可以这样做

import schedule
schedgen = schedule.SchedGen()
schedgen.set_rand_red()

或

from schedule import SchedGen
schedgen = SchedGen()
schedgen.set_rand_red()

此链接提供了 Python 如何使用 import statement 的一些信息。有效。
