问题描述
然后我将所有整数都转换为字符串,
您将整数 和 字符串都转换为 字节字符串
。对于字符串,它将使用碰巧为ASCII的默认字符编码,当您具有非ASCII字符时,它将失败。您要unicode
代替str
。
self.writer.writerow([unicode(s).encode("utf-8") for s in row])
最好在调用该方法之前将所有内容都转换为unicode。该类专门用于解析Unicode字符串。它并非旨在支持其他数据类型。
解决方法
我已经从[python网站] [1]复制了此脚本,这是另一个问题,但是现在编码存在问题:
import sqlite3
import csv
import codecs
import cStringIO
import sys
class UTF8Recoder:
"""
Iterator that reads an encoded stream and reencodes the input to UTF-8
"""
def __init__(self,f,encoding):
self.reader = codecs.getreader(encoding)(f)
def __iter__(self):
return self
def next(self):
return self.reader.next().encode("utf-8")
class UnicodeReader:
"""
A CSV reader which will iterate over lines in the CSV file "f",which is encoded in the given encoding.
"""
def __init__(self,dialect=csv.excel,encoding="utf-8",**kwds):
f = UTF8Recoder(f,encoding)
self.reader = csv.reader(f,dialect=dialect,**kwds)
def next(self):
row = self.reader.next()
return [unicode(s,"utf-8") for s in row]
def __iter__(self):
return self
class UnicodeWriter:
"""
A CSV writer which will write rows to CSV file "f",**kwds):
# Redirect output to a queue
self.queue = cStringIO.StringIO()
self.writer = csv.writer(self.queue,**kwds)
self.stream = f
self.encoder = codecs.getincrementalencoder(encoding)()
def writerow(self,row):
self.writer.writerow([s.encode("utf-8") for s in row])
# Fetch UTF-8 output from the queue ...
data = self.queue.getvalue()
data = data.decode("utf-8")
# ... and reencode it into the target encoding
data = self.encoder.encode(data)
# write to the target stream
self.stream.write(data)
# empty queue
self.queue.truncate(0)
def writerows(self,rows):
for row in rows:
self.writerow(row)
这次编码问题,当我运行它时,出现了这个错误:
Traceback (most recent call last):
File "makeCSV.py",line 87,in <module>
uW.writerow(d)
File "makeCSV.py",line 54,in writerow
self.writer.writerow([s.encode("utf-8") for s in row])
AttributeError: 'int' object has no attribute 'encode'
然后我将所有整数都转换为字符串,但是这次我得到了这个错误:
Traceback (most recent call last):
File "makeCSV.py",in writerow
self.writer.writerow([str(s).encode("utf-8") for s in row])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 1: ordinal not in range(128)
我已经在上面实现了处理Unicode字符的方法,但是它给了我这种错误。有什么问题以及如何解决?
