Replace Chinese Commas in Python Strings Using Regex

Introduction

The author shares a question from a Python group about handling a long Chinese string containing many terms separated by Chinese commas.

Original string example:

str1 = "校企联合，省料学，市科学，区科学，社会料学，料学院，料学家，科学实验室，国家料学，国防料学，能源料学，生命科学，计算机料学，国家料学，研究所长，研究所副所长，研究所合作"

Implementation

The solution uses a regular expression to match Chinese commas and replace them, ensuring the pattern uses the correct Unicode comma character.

import re
pattern = r'，'
result = re.sub(pattern, ',', str1)
print(result)

Key points: select the appropriate regex mode and use the Chinese comma character in the pattern; otherwise the match will fail.

Conclusion

The method successfully converts the Chinese commas to standard commas, demonstrating a simple way to preprocess Chinese text for further analysis with tools like pandas.
