26.模塊

第一個student.py

name = "Song Ke"

name_list = ["張三", "李四", "王五"]


def who_am_i(myName):
    print(f'my name is : {myName}')


class Student:
    def __init__(self, name, age, sex):
        self.__name = name
        self.__age = age
        self.__sex = sex

    def who_am_i(self):
        print(f'i am a student , {self.__name}, {self.__age}, {self.__sex}')

第二個app.py

# 模塊
# PYTHONPATH
import student
print(student.name)
print(student.name_list)
student.who_am_i("yang")

import sys
print("搜索路徑-------")
for line in sys.path:
    print(line)
