Question

我尝试使用utf-8文本格式加载.csv文件，并使用管道分隔符以cp1252（ansi）格式编写。以下代码适用于Python 3.6，但我需要它在Python 2.6中工作。但是，打开＆＃39;函数不允许Python 2.6中的编码关键字。

import datetime
import csv

# Define what filenames to read
filenames = ["FILE1","FILE2"]
infilenames = [filename+".csv" for filename in filenames]
outfilenames = [filename+"_out_.csv" for filename in filenames]

# Read filenames in utf-8 and write them in cp1252
for infilename,outfilename in zip(infilenames,outfilenames):
    infile  = open(infilename, "rt",encoding="utf8")
    reader = csv.reader(infile,delimiter=',',quotechar='"',quoting=csv.QUOTE_MINIMAL)

    outfile  = open(outfilename, "wt",encoding="cp1252")
    writer = csv.writer(outfile, delimiter='|', quotechar='"', quoting=csv.QUOTE_NONE,escapechar='\\')  
    for row in reader:
        writer.writerow(row)    

infile.close()
outfile.close()

我尝试了几种解决方案：

未定义编码。导致某些unicode字符出错
使用io库（io.open而不是open）。结果＆＃34;类型错误：无法将str写入文本流中的文本＆＃34;。

有没有人在Python 2.X中知道正确的解决方案？

这里可能有一些冗余代码，但我通过执行以下操作来实现此目的：

首先，我使用.decode和.encode函数进行了enconding以使其成为＆＃34; cp1252＆＃34;。
- 然后我从cp1252编码文件中读取csv并将其写入新的csv

...

import datetime
import csv

# Define what filenames to read
filenames = ["FILE1","FILE2"]


infilenames = [filename+".csv" for filename in filenames]
outfilenames = [filename+"_out_.csv" for filename in filenames]
midfilenames = [filename+"_mid_.csv" for filename in filenames]

# Iterate over each file
for infilename,outfilename,midfilename in zip(infilenames,outfilenames,midfilenames):

    # Open file and read utf-8 text, then encode in cp1252
    infile  = open(infilename, "r") 
    infilet = infile.read()
    infilet = infilet.decode("utf-8")
    infilet = infilet.encode("cp1252","ignore")

    #write cp1252 encoded file
    midfile = open(midfilename,"w")
    midfile.write(infilet)
    midfile.close()

    # read csv with new cp1252 encoding
    midfile = open(midfilename,"r")
    reader = csv.reader(midfile,delimiter=',', quotechar='"',quoting=csv.QUOTE_MINIMAL)

    # define output
    outfile  = open(outfilename, "w")
    writer = csv.writer(outfile, delimiter='|', quotechar='"',quoting=csv.QUOTE_NONE,escapechar='\\')

    #write output to new csv file
    for row in reader:
        writer.writerow(row)

    print("written file",outfilename)
    infile.close()
    midfile.close()
    outfile.close()

无法使用csv writer python 2.6将csv从utf-8转换为ansi
