上述代码中,我们首先导入re模块,然后使用re.compile()函数将要判断的字符串str2编译成正则表达式,设置re.IGNORECASE标志实现大小写不敏感的匹配。然后使用re.search()函数在str1中搜索匹配正则表达式的部分。如果找到匹配的部分,则打印"str1 contains str2 (case insensitive)“;如果没有找到匹配的部分,则打印"str1 d...
例如,我们可以通过str.contains检查各个电⼦邮件地址是否含有"gmail": In [171]: data.str.contains('gmail') Out[171]: Dave False Rob True Steve True Wes NaN dtype: object 1. 2. 3. 4. 5. 6. 7. 也可以使⽤正则表达式,还可以加上任意re选项(如IGNORECASE): In [172]: pattern Out[172]:...
The message field matches the start of the warning message printed; this match is case-insensitive. The category field matches the warning category. This must be a class name; the match test whether the actual warning category of the message is a subclass of the specified warning category. The...

Expected <foo>tobecase-insensitive equalto<BAR>, but wasnot. 在发现assertpy之前我也想写一个类似的包,尽可能通用一些。但是现在,我为毛要重新去造轮子?完全没必要! 总结 断言在软件系统中有非常重要的作用,写的好可以让你的系统更稳定,也可以让你有更多面对(女)对象的时间,而不是在调试代码。
