功能无法正确返回列表

Question

处理此代码。当程序运行时，print(random_generator)实际上并没有打印出引用，它只是在shell中显示<function 40x....>。有关为什么会发生这种情况的任何提示？

import time  
import random 
quotes= ["Life is too short, so savior every moment", 
"Here's to the crazy ones, the rebels, square pegs in round holes",       
"You miss all the shots you don't take"]



def random_generator():   #RandomQuoteGenerator
    return random.choice(quotes)

timeout = 1     #Timer 
first_time = time.time()
last_time = first_time
while(True):
    pass #do something here
    new_time = time.time()
    if  new_time - last_time > timeout:
        last_time = new_time
        print(random_generator) 
        print ("Its been %f seconds" % (new_time - first_time))  #TimeCheck

Answer 1

此外，如果您想要实际打印random_generator的结果，您需要实际调用它。

你有：

print(random_generator)

你可能想要：

print(random_generator())
