UnicodeDecodeError: &#39;charmap&#39; 編解碼器無法解碼位置 295 中的字節 0x9d：字符映射到<undefined>

Question

我正在嘗試從書中運行這個程序。 我創建了名為“alice_2.txt”的文件

def count_words(filename):
    """Count the approximate number of words in a file."""
    try:
        with open(filename) as f_obj: 
            contents = f_obj.read()
    except FileNotFoundError:
        msg = "Sorry, the file " + filename + " does not exist."
        print(msg)
    else:
        # Count approximate number of words in the file.
        words = contents.split()
        num_words = len(words)
        print("The file " + filename + " has about " + str(num_words) +
            " words.")
            
filename = 'alice_2.txt'
count_words(filename)

但我不斷收到此錯誤消息

UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 295: character maps to <undefined>

任何人都可以解釋這意味着什么，以及如何解決它？

Answer 1

您正在嘗試使用無法存儲文件中字符的編碼。 例如ɛ不能在 ascii 中打開，因為它沒有有效的 ascii 代碼。

嘗試使用utf-8打開文件。

with open(filename, encoding='utf8') as f_obj:
    pass
    # DO your stuff
