Python模組詳解

• 自定義模組
• 模組匯入

自定義模組

__all__ = ['add', 'number']  #    [使用*可以訪問到的內容]#1

number = 100
name = 'name'

def add(*args):
    if len(args) > 1:
        sum = 0
        for i in args:
            sum += i
        return sum
    else:
        print('至少傳入兩個引數')
        return 0


def
 
 minus(*args):
    if len(args) > 1:
        m = 0
        for i in args:
            m -= i
        return m
    else:
        print('至少傳入兩個引數')
        return 0


class Calculate:
    def __init__(self, num):
        self.num = num

    def test(self):
        print('正在運算')

    @classmethod
    def
 
 test1(cls):
        print('calculate中的類方法')

def test():
    print('我是測試')

print('__name__:', __name__) #2

if __name__ == '__main__':  

    test()

import calculate

list1 = [1, 2, 3, 4]
result = calculate.add(*list1)
print(result)
print(calculate.number)
calculate.Calculate.test1()

import會載入模組裡的程式碼到記憶體，如果模組中存在函式呼叫，也會執行該呼叫

from calculate import add, number, Calculate
#from calculate import *
list1 = [1, 2, 3, 4]
result = add(*list1)
sum = result + number
print(sum)
c = Calculate(80)
c.test1()
