我们可以使用Python实现exact match指标的计算。首先,我们将对每个候选文本和目标文本进行文本清理,例如去除标点符号、转换为小写等。然后,我们将检查生成的候选文本是否与目标文本完全匹配,即是否一字不差地一致。 一个简单的实现是使用Python的string模块中的函数来完成这个任务。我们可以使用string模块中的函数比较两个...
Python 的re库不直接支持模糊匹配,但我们可以利用一些特殊的模式实现。 例如,如果我们想匹配包含“excat”或“exact”的字符串,我们可以使用re模块的功能通过正则表达式构建模糊匹配的条件: # 模糊匹配的正则表达式fuzzy_pattern=r"ex(a|c)t"# 搜索fuzzy_match=re.search(fuzzy_pattern,text)iffuzzy_match:print("...

The expected output in the docstring examples is sensitive to minor changes as it requires exact matching in the expected output. If even a single character doesn’t match it leads to test failures. When to Choose Doctest is a suitable option if you want to showcase code examples in your ...

Either escapes special characters (permitting you to match characters like '*', '?', and so forth), or signals a special sequence; special sequences are discussed below. If you’re not using a raw string to express the pattern, remember that Python also uses the backslash as an escape se...
