如何将pandas数据框转换为unicode?

How to convert pandas dataframe to unicode?

`messages=pandas.read_csv('data/SMSSpamCollection',sep='\t',quoting=csv.QUOTE_NONE,names=["label", "message"])
def split_into_tokens(message):
  message = unicode(message, 'utf8')  # convert bytes into proper unicode
  return TextBlob(message).words


messages.head().apply(split_into_tokens(messages))`

出现错误

Traceback (most recent call last):
File "minor.py", line 46, in <module>
messages.head().apply(split_into_tokens(messages))
File "minor.py", line 42, in split_into_tokens
message = unicode(message, 'utf8')  # convert bytes into proper unicode
TypeError: coercing to Unicode: need string or buffer, DataFrame found

推荐答案

更改代码

messages.head().apply(split_into_tokens(messages))

到

messages.head().apply(split_into_tokens)

在将"apply"与功能结合使用时(例如您的情况)不需要传递参数，因为您的代码表明它正在传递一个数据帧，该数据帧在执行时产生错误.

while using 'apply' with a funtion like in your case passing parameters is not required, as your code shows it is passing a dataframe which is giving error on execution.
