如何在 python 中使用反斜杠和变量创建字符串？

Question

我正在尝试在 Windows 计算机上执行此命令：

dir \\hostname\sapmnt\SID\SYS\profile\SID_*04_hostname /b /a-d

到目前为止，我有以下代码：

cmd_drive = r"\\"
local_hostname = "hostname"
current_sid = "SID"
currentline_instance_number = "04"
cmd_pf = os.path.join(cmd_drive, local_hostname, "sapmnt", current_sid, "SYS", "profile")
cmd_pf = cmd_pf + str(current_sid) + "_*" + str(currentline_instance_number) + "_" + str(currentline_host)
cmd_pf = "dir " + cmd_pf + " /b /a-d"
print(cmd_pf)

产生以下输出：

dir \\hostname\sapmnt\SID\SYS\profileSID_*04_hostname /b /a-d

因此，我需要在字符串的最后部分之前有一个反斜杠 ("SID_*04_hostname /b /广告”)

添加“\\”以在所需位置创建反斜杠：

cmd_drive = r"\\"
    local_hostname = "hostname"
    current_sid = "SID"
    currentline_instance_number = "04"
    cmd_pf = os.path.join(cmd_drive, local_hostname, "sapmnt", current_sid, "SYS", "profile")
    cmd_pf = cmd_pf + "\\" + str(current_sid) + "_*" + str(currentline_instance_number) + "_" + str(currentline_host)
    cmd_pf = "dir " + cmd_pf + " /b /a-d"
    print(cmd_pf)`
