我正在查询 Twitter API 并接收 utf-8 编码的答案。现在我想用format()函数将这些答案保存在一个字符串中。这就是我到目前为止所拥有的（我已经尝试了很多替代方案）。

for user in userInfos:
    tName = user["name"] if user["name"] is not None else ""
    tLocation = user["location"] if user["location"] is not None else ""
    tProfileImageUrl = user["profile_image_url"] if user["profile_image_url"] is not None else ""
    tCreatedAt = user["created_at"] 
    tFavouritesCount = user["favourites_count"] 
    tUrl = user["url"] if user["url"] is not None else ""
    tId = user["id"] 
    tProtected = user["protected"] 
    tFollowerCount = user["followers_count"]
    tLanguage = user["lang"]
    tVerified = user["verified"]
    tGeoEnabled = user["geo_enabled"]
    tTimeZone = user["time_zone"] if user["time_zone"] is not None else ""
    tFriendsCount = user["friends_count"]
    tStatusesCount = user["statuses_count"]
    tScreenName = user["screen_name"]

    # Custom characteristics
    age = utl.get_age_in_years(birthdayDict[str(tId)])

    # Follower-friend-ratio
    if tFriendsCount > 0:
        foRatio = float(tFollowerCount)/float(tFriendsCount)
    else:
        foRatio = ""

    # Age of account in weeks
    numWeeks = utl.get_age_in_weeks(tCreatedAt)

    # Tweets per time
    tweetsPerWeek = float(tStatusesCount) / numWeeks
    tweetsPerDay = tweetsPerWeek / 7.0

    in_users.remove(str(tId))

    outputList = [str(tName),
                  str(tScreenName),
                  str(tProfileImageUrl),
                  str(tLocation),
                  str(tCreatedAt),
                  str(tUrl),
                  str(age),
                  str(tStatusesCount),
                  str(tFollowerCount),
                  str(tFriendsCount),
                  str(tFavouritesCount),
                  str(foRatio),
                  str(tLanguage),
                  str(tVerified),
                  str(tGeoEnabled),
                  str(tTimeZone),
                  str(tProtected),
                  str(numWeeks),
                  str(tweetsPerWeek),
                  str(tweetsPerDay)]

    pprint.pprint(outputList)
    fOut.write("{}{}{}{}{}{}{}\n".format(twitterUsers[str(tId)], outputDelimiter, outputDelimiter.join(outputList), outputDelimiter, utl.get_date(), outputDelimiter, utl.get_time()))

当 tName/tLocation 包含诸如 \xe4 之类的内容时，str(tName)、str(tLocation) 等会给我错误

ERROR:__main__:'ascii' codec can't encode character u'\xe4' in position 10: ordinal not in range(128)
Traceback (most recent call last):
  File "../code/userinfo_extraction_old.py", line 167, in <module>
    outputList = [str(tName),
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 10: ordinal not in range(128)

我试图了解它是如何工作的，但我无法弄清楚这里出了什么问题。我也尝试过使用 unicode() 而不是 str() ...没有机会。

要将unicode数据转换为str您需要指定编码。使用tName.encode('utf8')等。

你可能想阅读 Python 和 Unicode：
