python - Subprocess.Popen: How to pass arguments without whitespace

Question

Mighty people of Stackoverflow,

I want to execute

./namecoind name_new d/<name>

in a Python script with subprocess.popen where 'name' is a variable within the script. There are no spaces allowed between 'd/' and the variable. I tried this:

p = subprocess.Popen(["./namecoind", "name_new", "d/", domainname])

but this does not work, because this adds an ws between d/ and 'domainname'.

So, what to?

Thanks in advance!

空白不进入图片；subprocess.Popen如果您将列表传递给它（而不是字符串），则不会通过外壳程序，因此它不会在空格上拆分命令行。该参数只需要作为单个列表项发送：

p = subprocess.Popen(["./namecoind", "name_new", "d/" + domainname])
