HomeBackend DevelopmentPython TutorialSummary of python Chinese garbled problems

Explain clearly at once the issue of garbled Chinese characters in python2.
In order to help beginners no longer worry about garbled Chinese characters in python2!

Please see Brother Huang, the teacher of Python training class at Diaim Company, for details:
1. The code module you write needs to specify the encoding
If the code does not specify the coding, python will default all characters to ASCII code,
ASCII code only It supports 256 characters. ASCII code does not support Chinese, so an error is reported.
So you need to write #coding:utf-8 or #coding:gbk before the code
But generally write #coding:utf-8

2. All encodings inside python2 are unified to unicode
unicode can handle all languages ​​​​in the world character.
utf-8 is an implementation form of unicode, so you need to write #coding:utf-8 before the code

3. Encoding conversion
Keep in mind that the internal encoding of python2 is unicode.
Other encoding decode() is unicode, and then Encoding encode() is the encoding you specify, so there will be no garbled characters.

4. When collecting web pages
Code designation #coding:utf-8
If the encoding of the web page is gbk
It needs to be processed like this:
html = html.decode('gbk').encode('utf-8')

5. You can also write #coding:gbk before the code, but you must also ensure that your code file is saved in gbk. This problem will occur under Windows.

6. Problems with Chinese characters in dictionary keys or values ​​
#coding:utf-8
dict1 ={1:'python weekend training class',2:'Consultation 010-68165761 QQ: 1465376564'}

print dict1
# This output does not display Chinese characters, but displays other encodings of Chinese characters

dict2 ={1:'python video training class',2:'Consultation 010-68165761 QQ: 1465376564'}
for key in dict2:
print dict2[key ]

7. Unicode Chinese character encoding is written into a text file
Needs to be converted according to the encoding of the text file
Can encode('utf-8') or encode('gbk')

Summary: All errors that appear in the error message The error contains "ASCII", which means that the Chinese character encoding is not specified.


----Get the encoding type of the string--------------------------------------------- --------------------------
>>> date = urllib2.urlopen("http://www.baidu.com ")
>>> d = date.read()
>>> import chardet
>>> chardet.detect(d)
{'confidence': 0.99, 'encoding': 'utf-8'}

You can manage different Python versions by using pyenv, venv and Anaconda. 1) Use pyenv to manage multiple Python versions: install pyenv, set global and local versions. 2) Use venv to create a virtual environment to isolate project dependencies. 3) Use Anaconda to manage Python versions in your data science project. 4) Keep the system Python for system-level tasks. Through these tools and strategies, you can effectively manage different versions of Python to ensure the smooth running of the project.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
