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, f, 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", which is encoded in the given encoding. """ def __init__(self, f, dialect=csv.excel, encoding="utf-8", **kwds): # Redirect output to a queue self.queue = cStringIO.StringIO() self.writer = csv.writer(self.queue, dialect=dialect, **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", line 87, in <module> uW.writerow(d) File "makeCSV.py", line 54, 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?
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。
unicode
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。
