如何使用python和re？

将数字后面的空格替换为逗号

例如，

0,1,0 12 13 - ＆gt; 0,1,0,12,13;

import re

text = "0, 1, 0 12 13"    
matches = re.sub(r'(\d+)\s','*,', text)
print(matches)

但这给了我 0,1，*，*，*，

Answer 1

另一种方式，没有重新：

text = "0, 1, 0 12 13" 
text = text.replace(',', '') #We remove the commas (to leave them all the same)
text.replace(' ', ', ')      # We replace spaces by comma and space
