问题:利用Python对文本进行分析时,出现UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xef in position 0: ordinal not in range(128)
先看下面这段Python代码:
filename = 'alice.txt'
try:
with open(filename) as f_obj:
contents = f_obj.read()
except FileNotFoundError:
msg = "Sorry, the file " + filename + " does not exist."
print(msg)
else:
# 计算文件大致包含多少单词
words = contents.split()
num_words = len(words)
print("The file " + filename + " has about " + str(num_words) + " words.")
运行的结果如下:
File "/Users/tiramisu/python_work/10/alice.py", line 5, in <module>
contents = f_obj.read()
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/encodings/ascii.py", line 26, in decode
return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128)
正是出现了标题中所说的UnicodeDecodeError。
这个问题我在网上找了很多方法,都没能成功解决。最后经过一番波折,终于成功解决了这个问题。
方法就是:
在打开文本的时候,就用utf-8
格式。
就我这个代码而言,只需将第3行的
with open(filename) as f_obj:
修改为:
with open(filename, encoding='utf-8') as f_obj:
即可。
修改后再次运行改代码,结果如下:
至此,该问题已经解决。
