Python has four methods for reading Chinese: reading directly, specifying encoding, processing escape characters, and using third-party libraries. Directly read files suitable for the default UTF-8 encoding, specify the encoding to specify non-UTF-8 encoding, handle escape characters to handle escape characters, and third-party libraries can automatically detect file encoding.
How to read Chinese in Python
Read directly:
Python 3 supports Unicode encoding by default, so Chinese files can be read directly.
with open('test.txt', 'r', encoding='utf-8') as f: text = f.read() print(text)
Specify encoding:
If the file is not the default UTF-8 encoding, you need to specify the correct encoding format.
with open('test.txt', 'r', encoding='gbk') as f: text = f.read() print(text)
Handling escape characters:
If the Chinese file contains escape characters (for example, \uxxxx
), you need to use codecs
module for processing.
import codecs with codecs.open('test.txt', 'r', encoding='utf-8') as f: text = f.read() print(text)
Use third-party libraries:
Some third-party libraries, such as chardet
and universal-encoding-detector
, File encoding can be automatically detected.
import chardet with open('test.txt', 'rb') as f: text = f.read() encoding = chardet.detect(text)['encoding'] print(encoding)
Other notes:
- Ensure that the encoding format of the file is consistent with the encoding format specified in the code.
- If the file is large, it can be read in batches to avoid memory overflow.

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.
