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("...
importre# Lets use a regular expression to match a date string. Ignore# the output since we are just testing if the regex matches.regex =r"([a-zA-Z]+) (\d+)"ifre.search(regex,"June 24"):# Indeed, the expression "([a-zA-Z]+) (\d+)" matches the date string# If we want,...
Conditional Independence Assumption (CIA)假定: 那么这个方法实际操作起来通常就是称之为Exact matching(精准匹配),也就是对于每一个 T=1的用户,我们从 T=0的分组里找一个变量 一模一样的用户,在这个X的条件下,满足T与Y相互独立,此时直接比较两组用户观察结果 的差异就可以得到结论,但是,“匹配用户的变量 完全...

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 ...
