為什么我在使用多行引號時出現語法錯誤？

Question

這是代碼：

'''

file_path = (r'C:\Users\Luka\Desktop\Pyhton exercises\pi_digits.txt')

with open(file_path) as file_object:
    contents = file_object.read()
    print(contents)
    #print(contents.rstrip()) # rstrip should remove blank space at the end


'''

filename = ("prova.txt")

with open(filename) as file_object:
    for line in file_object:
        print(line)

Answer 1

問題在於三引號之間的file_path變量。 C:\開始一個八字符的 Unicode 轉義。 在您的代碼中，轉義符后跟字符U ，這是無效的。

加倍你的反斜杠以逃避它們，例如：

"""
file_path = (r'C:\\Users\\Luka\\Desktop\\Pyhton exercises\\pi_digits.txt')

with open(file_path) as file_object: contents = file_object.read() print(contents) #print(contents.rstrip()) # rstrip should remove blank space at the end

"""

filename = "prova.txt"
