python - 地址错误 : (unicode error) 'unicodeescape' codec can't decode

Question

当我对图像使用地址时，显示图像的代码出现语法错误。

from tkinter import *
import numpy as np
import matplotlib.pyplot as plt
from PIL import Image

Scare = Tk()
Scare.title('?????')
Countdown = 2
CountTotal = 2
CountTotal = IntVar()

def CountdownWork():
    global Countdown
    if Countdown > 0:
        Countdown = Countdown -1
        CountTotal.set(Countdown)
        Scare.after(1000, CountdownWork)
    else:
        ImageAddress = 'C:\Users\KINSLED\Desktop\New folder\ScareTest.jpg'
        ImageItself = Image.open(ImageAddress)
        ImageNumpyFormat = np.asarray(ImageItself)
        plt.imshow(ImageNumpyFormat)
        plt.draw()
        plt.pause(5) # pause how many seconds
        plt.close()



Count = Label(Scare, font=('arial', 10, 'bold'), textvariable=CountTotal, 
bd=30, bg='SeaGreen1', justify='right').grid(row=7,columnspan=8)

CountdownWork()

Scare.mainloop()

语法错误是突出显示 ImageAdress 中等号之后的空格。

错误是:

(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated\UXXXXXXXX escape

Answer 1

In Python strings, the backslash "\" is a special character, also called the "escape" character. It is used in representing certain whitespace characters: "\t" is a tab, "\n" is a newline, and "\r" is a carriage return.

我认为错误是引用了您的地址，特别是其中的特殊字符 "\"。您不能在字符串中使用 "\"，因为它会转义字符串。您可以尝试在您的地址中使用 "\\"，我认为这应该可行。
