python中類的應用實例

import numpy as np

class Generate(object):
    def __init__(self):
        self.group_images()
        self.lock = figure # 這裏只是把變量self.lock指向了figure這個函數，沒有調用這個函數
        self.z = with_bracket()

    def group_images(self):
        print('hello')

def figure():
    print('figure')

def with_bracket():
    print('with_bracket')

x = Generate()
x.lock() # 這裏才調用了figure函數

結果：

hello
with_bracket
figure
