How to read Chinese in python

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.

<code class="python">with open('test.txt', 'r', encoding='utf-8') as f:
    text = f.read()
    print(text)</code>

Specify encoding:

If the file is not the default UTF-8 encoding, you need to specify the correct encoding format.

<code class="python">with open('test.txt', 'r', encoding='gbk') as f:
    text = f.read()
    print(text)</code>

Handling escape characters:

If the Chinese file contains escape characters (for example, \uxxxx), you need to use codecs module for processing.

<code class="python">import codecs

with codecs.open('test.txt', 'r', encoding='utf-8') as f:
    text = f.read()
    print(text)</code>

Use third-party libraries:

Some third-party libraries, such as chardet and universal-encoding-detector, File encoding can be automatically detected.

<code class="python">import chardet

with open('test.txt', 'rb') as f:
    text = f.read()

encoding = chardet.detect(text)['encoding']
print(encoding)</code>

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.
