[汉字编码报错] UnicodeEncodeError- 'ascii' codec can't encode characters in position 0-1- ordinal not in r

原始代码

# -*- coding:utf-8 -*-

import pandas as pd
import jieba
def cut_msg(ustr):
# ustr = ustr.encode("raw_unicode_escape").decode("raw_unicode_escape").encode("utf8")
return " ".join(jieba.lcut(str(ustr)))

fp = "gray.xlsx"
df = pd.read_excel(fp)
df["msg"] = df["msg"].map(cut_msg)
li = df["msg"]
with file(fp.replace(".xlsx", ".txt"), "wb") as wf:
for e in li:
wf.write(e.encode("utf8")+"\n")

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

解决方案

ustr.encode("raw\_unicode\_escape").decode("raw\_unicode\_escape").encode("utf8") # 这里的 utf8 根据实际数据编码而定

# -*- coding:utf-8 -*-

import pandas as pd
import jieba
def cut_msg(ustr):
ustr = ustr.encode("raw_unicode_escape").decode("raw_unicode_escape").encode("utf8") # 这里的 utf8 根据实际数据编码而定
return " ".join(jieba.lcut(str(ustr)))
