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

本文主要是介绍[汉字编码报错] UnicodeEncodeError- 'ascii' codec can't encode characters in position 0-1- ordinal not in r，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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")

解决方案

加入编码和解码语句
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

如下：

# -*- 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)))
