Python SyntaxError: EOL while scanning string literal

python中字符串的最后一个字符是斜杠会导致出错：SyntaxError: EOL while scanning string literal

 img = Image.open(r"C:\Users\Ifand\Top250_movie_images\" + name)

改成

 img = Image.open("C:\\Users\\Ifand\\Top250_movie_images\\" + name)

还有一种错误

i = Image.open("C:\Users\Ifand\Top250_movie_images\2019\“大”人物.jpg")

改成

i = Image.open(r"C:\Users\Ifand\Top250_movie_images\2019\“大”人物.jpg")

或者

i = Image.open("C:\\Users\\Ifand\\Top250_movie_images\\2019\\“大”人物.jpg")
