Python3 resolve to read Chinese txt file encoding problem

Today small for everyone to share a Python3 solve the problem txt file encoding to read Chinese, have a good reference value, we want to help. Come and see, together follow Xiaobian
description of the problem

Trying to write a Wordcloud with Python, there have been coding problems.

Some say the Internet blog shining after Tian Tian to change to change, the result is turned into a "UnicodeDecodeError: 'utf-8' codec can not decode byte ..." error.

Fiddle day ah, TXT (here is my heart holds many lessons for expression). Finally, simply write the simplest to read the file, or even an error. So it is not considered txt coding problem, because the txt file is read on a Mac new plain text file, not a moment to see where to find the code, finally copied to the Windows system, see the txt file encoding, turned out to be ASCII, not my favorite utf-8, Mac you betrayed my trust in you a lot of ah! [epsilon] (┬┬﹏┬┬) 3

Solution

The encoding format of txt file can be changed to utf-8

Further, when opening the file, to add a third parameter encoding = 'utf8' (no bar).

with open('./test3.txt','r',encoding='utf8') as fin:
  for line in fin.readlines():
    line = line.strip('\n')

Attached below source word cloud of the first successful display (refer others online, notes in great detail)

import jieba
import jieba.analyse
from matplotlib import pyplot as plt
from scipy.misc import imread
from wordcloud import WordCloud,STOPWORDS,ImageColorGenerator
  
# 1.读取数据
with open("./test.txt","r",encoding="utf8") as f:
  text = f.read()
  
# 2.基于 TextRank 算法的关键词抽取,top50
keywords = jieba.analyse.textrank(text, topK=50, withWeight=False, allowPOS=('ns', 'n', 'vn', 'v'))
file = ",".join(keywords)
  
# 指定中文字体，不然中文显示框框
font = r'./HYQiHei-25J.ttf'
print(file)
# 指定背景图,随意
image = imread('cake.jpg')
wc = WordCloud(
  font_path=font,
  background_color='white',#背景色
  mask=image,#背景图
  stopwords=STOPWORDS,#设置停用词
  max_words=100,#设置最大文字数
  max_font_size=100,#设置最大字体
  width=800,
  height=1000,
  
)
  
#生成词云
image_colors = ImageColorGenerator(image)
wc.generate(file)
  
# 使用matplotlib,显示词云图
plt.imshow(wc) #显示词云图
plt.axis('off') #关闭坐标轴
plt.show()
# 保存图片
wc.to_file('news.png')
