UnicodeEncodeError: 'ascii' 编解码器无法对位置 7 的字符 u'xe9' 进行编码:序号不在范围内 (128)

问题描述

我有这个代码:

    printinfo = title + "	" + old_vendor_id + "	" + apple_id + '
'
    # Write file
    f.write (printinfo + '
')

但是我在运行时遇到这个错误:

But I get this error when running it:

    f.write(printinfo + '
')
UnicodeEncodeError: 'ascii' codec can't encode character u'xe9' in position 7: ordinal not in range(128)

写这个太麻烦了:

请提供任何想法，不知道如何解决.

Any ideas please, not sure how to fix.

干杯.

更新:这是我的大部分代码，所以你可以看到我在做什么:

UPDATE:This is the bulk of my code, so you can see what I am doing:

def runLookupEdit(self, event):
    newpath1 = pathindir + "/"
    errorFileOut = newpath1 + "REPORT.csv"
    f = open(errorFileOut, 'w')

global old_vendor_id

for old_vendor_id in vendorIdsIn.splitlines():
    writeErrorFile = 0
    from lxml import etree
    parser = etree.XMLParser(remove_blank_text=True) # makes pretty print work

    path1 = os.path.join(pathindir, old_vendor_id)
    path2 = path1 + ".itmsp"
    path3 = os.path.join(path2, 'metadata.xml')

    # Open and parse the xml file
    cantFindError = 0
    try:
        with open(path3): pass
    except IOError:
        cantFindError = 1
        errorMessage = old_vendor_id
        self.Error(errorMessage)
        break
    tree = etree.parse(path3, parser)
    root = tree.getroot()

    for element in tree.xpath('//video/title'):
        title = element.text
        while '
' in title:
            title= title.replace('
', ' ')
        while '	' in title:
            title = title.replace('	', ' ')
        while '  ' in title:
            title = title.replace('  ', ' ')
        title = title.strip()
        element.text = title
    print title

    # Remove the comment tags
    comments = tree.xpath('//comment()')
    q = 1
    for c in comments:
        p = c.getparent()
        if q == 3:
            apple_id = c.text
        p.remove(c)
        q = q+1

    apple_id = apple_id.split(':',1)[1]
    apple_id = apple_id.strip()
    printinfo = title + "	" + old_vendor_id + "	" + apple_id

    # Write file
    # f.write (printinfo + '

    f.write(printinfo.encode('utf8') + '
')
f.close()

推荐答案

在写入文件之前，您需要显式编码 Unicode，否则 Python 会使用默认的 ASCII 编解码器为您编码.

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

选择一种编码并坚持使用:

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '
')

或使用 io.open() 创建一个文件对象，该对象将在您写入文件时为您编码:

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')
