我不能用d打印一些东西给控制台

Question

我无法在定义的函数中打印任何内容。解决办法是什么

import cv2
def ResimFarkBul(Resim1,Resim2):
    Resim2 = cv2.resize(Resim2,(Resim1.shape[1],Resim1.shape[0]))
    Fark_Resim = cv2.absdiff(Resim1,Resim2)
    Fark_Sayı = cv2.countNonZero(Fark_Resim)
    print(Fark_Sayı)

任何帮助都将不胜感激

Answer 1

创建函数后忘记调用它：

你需要的只是简单的称呼它

 ResimFarkBul(arg1, arg2)

您创建了一个带有参数的函数，这意味着当您调用它时，需要为它提供参数

示例：

    #create function
    def print_something(arg1, arg2):
       print("arg1 =>", arg1)
       print("arg2 =>", arg2)

    # now you need to call it
    print_something("spam", "eggs") # this will print "arg1 => spam", "arg2 => eggs"
   # if you call print_something() you ll get Error because you didnt give any arguments and declared the functions with arguments
