我需要在Win32上运行这三个命令以进行性能分析/代码覆盖率报告.
vsperfcmd /start:coverage /output:run.coverage
helloclass
vsperfcmd /shutdown

我不能一个地运行一个命令,因为应该在vsperfcmd的相同进程中分析helloclass可执行文件.
我想到的是制作一个批处理文件来运行这三个命令,并在Python中运行批处理文件.但是,我认为python应该有一种方法来执行启动shell和运行命令的等效操作.
import subprocess
cmdline = ["cmd", "/q", "/k", "echo off"]
cmd = subprocess.Popen(cmdline, stdin=subprocess.PIPE, stdout=subprocess.PIPE, shell=True)
batch = b"""\
rem vsinstr -coverage helloclass.exe /exclude:std::*
vsperfcmd /start:coverage /output:run.coverage
helloclass
vsperfcmd /shutdown
exit
"""
cmd.stdin.write(batch)
cmd.stdin.flush() # Must include this to ensure data is passed to child process
result = cmd.stdout.read()
print(result)

ElementTree是否具有添加兄弟节点的功能?如果没有,我想我需要一个函数来获取父节点并添加一个子节点,我该怎么办呢?
我有C#类如下:
public class ClassInfo {
public string ClassName;
public int BlocksCovered;
public int BlocksNotCovered;
public ClassInfo() {}
public ClassInfo(string ClassName, int BlocksCovered, int BlocksNotCovered)
{
this.ClassName = ClassName;
this.BlocksCovered = BlocksCovered;
this.BlocksNotCovered = BlocksNotCovered;
}
}

这段代码出了什么问题?
我有一个正则表达式来寻找:ABC:`hello`模式.这是代码.
format =r".*\:(.*)\:\`(.*)\`"
patt = re.compile(format, re.I|re.U)
m = patt.match(l.rstrip())
if m:

当模式在一行中发生一次时它很有效,但是有一个例子":tagbox:`Verilog`:tagbox:`Multiply`:tagbox:`VHDL`".它只找到最后一个.
我怎样才能找到所有这三种模式?
根据Paul Z的回答,我可以使用这段代码
format = r"\:([^:]*)\:\`([^`]*)\`"
patt = re.compile(format, re.I|re.U)
for m in patt.finditer(l.rstrip()):
tag, value = m.groups()
print tag, ":::", value

结果
tagbox ::: Verilog
tagbox ::: Multiply
tagbox ::: VHDL
