打印 Python def 的结果

Question

I want to read the date and time of a image by using Pillow. And now I want to print the result of the def to be shure I got the Date and Time. But when I type print(defname) I just get some weird numbers as the output.

My code:

import os
import time
import shutil 
import re
from PIL import Image, ExifTags
from PIL.ExifTags import TAGS

def get_date_taken(path):
    return Image.open(r"E:\insert_folder\DSC_3389.jpg")._getexif()[36867]

print(get_date_taken)

One more thing... If you understand what I want to do and if you understand my code, could you pls check if there is any fault in my code? Thanks to you guys! <3

Answer 1

You are not calling the function, you are just printing a pointer to that function - this the memory address where the function is stored. In order to execute the function, add parenthesis.

get_date_taken("your\\path\\here")

Also, what you are calling def and defname are called functions in Python.

Answer 2

You have to execute your function:

It is

print(get_date_taken(""))

not

print(get_date_taken)

Answer 3

you are just printing the definition of your function. To print the return value you have to call your function with the path:

print(get_date_taken("path of your image"))

Answer 4

Functions take magnificent things called parameters. You need to fill get_date_taken with a parameter such as get_date_taken("IMG_0001")
