什么是最好的 python 正则表达式来排除一对大括号之间的逗号的单个实例？
[英]What is the best python regular expression to exclude only a single instance of a comma between a pair of curly brackets?
问题描述
If the line contains more than one comma, I want it returned.
如果该行包含多个逗号，我希望它返回。
For example, in the following lines I want to return all the lines except {,} .例如，在以下几行中，我想返回除{,}之外的所有行。
{,,,}
{abskdjf}
{,}

Can't you just match on that exactly?你不能完全匹配吗？ For example in Python if the text was a variable called text then re.sub(r"{,}", "", text)例如在 Python 中，如果文本是一个名为 text 的变量，那么re.sub(r"{,}", "", text)
