如何在 c++ 中使用 system() 来运行包含空格的 python 脚本

Question

I wish to run a python script in c++ code but the address path contains spaces.
Here is what I'm trying to do:

string python = "\"D:\\my folder\\python.exe\"";
string script = "\"D:\\my scripts\\hello.py\"";
string arg = "\"argument 1\"";
string cmd= python + " " + script + " " + arg;
system(cmd.c_str());

Here cmd "\"D:\\my folder\\python.exe\" \"D:\\my scripts\\hello.py\"" "\"argument 1\""
which is in text form, expected to be executed as
"D:\my folder\python.exe" "D:\my scripts\hello.py" "argument 1" as command line, but this fails to execute with an error ->'D:\my' is not recognized as an internal or external command.

But the same command "D:\my folder\python.exe" "D:\my scripts\hello.py" works fine in command prompt?
Please suggest in c++ how to execute python script having space in the path and pass an argument to the script.

Alright, I found a way to get it to work with a system() I tried with exec but still had some issues there. one needs to cover the entire command in double-quotes.

In my case it should be "\"\"D:\\my folder\\python.exe\" \"D:\\my scripts\\hello.py\"" "\"argument 1\"\""
