This line of code sets the environment variable PATH to include two new directories:
- dir_path/../../x64/Release
- dir_path/../../bin
The semicolon (;) is used as a separator between different directories in the PATH variable.
Assuming that dir_path is a variable that holds the path of the current working directory, this code is trying to add two new directories to the PATH variable, which could be useful if there are executables or libraries located in those directories that need to be accessed by the current Python script.
