# 4. re.findall - named group #接着再来演示一下,如果findall中,使用了带命名的group(named group)的结果: foundAllPicGroups=re.findall(singlePicUrlP_namedGroup, searchVsFindallStr); #则也是可以去查找所有的匹配到的字符串的 #然后返回的是列表的值 print"

Named by Van Rossum for his interest in the Monty Python movies, Python initially did not gain the same heavy support as Perl. Over time, however, the advocate count grew, and the comp.lang.python usenet group was founded in 1994. Unlike GNU, Python was originally released completely “...
obj=re.match(info).group(1)ifre.match(info)elseNone 正则表达式匹配 从上面的代码可以观察到,我们在一次匹配中重复计算了 re.match(info)。这会减慢该程序的执行速度,而且数据量越大减慢得越明显。上面的代码可以重写为如下形式,从而避免重复计算: obj=match.group(1)ifmatch:=re.match(info)elseNone 使用:...

This training loop can be re-used across algorithms as it makes a minimal number of assumptions about the structure of the data. TensorDict supports multiple tensor operations on its device and shape (the shape of TensorDict, or its batch size, is the common arbitrary N first dimensions of ...
