[Python] Why does my Python program run twice when I execute it by double-clicking the .py...

I’m learning Python and I noticed something strange.
When I double-click my Python file (.py) on Windows to run it, the program seems to run twice.

Here is a simple example:

print("Program started")

name = input("Enter your name: ")
print("Hello,", name)


When I run the file by double-clicking it:

• 
  The console opens
  
  
• 
  Prints “Program started”
  
  
• 
  Immediately closes and reopens again, asking for input
  
  
• 
  Sometimes the console closes before I can read the output
  

But when I run the same code from VS Code or CMD, it runs normally.

My questions:

1. 
   Why does double-clicking a .py file cause the console to open/close so quickly or run twice?
   
   
2. 
   Is there a correct way to run Python scripts by double-clicking so they don’t auto-close?
   
   
3. 
   Should beginners always use CMD/VS Code instead of double-clicking .py files?
   

I tried searching, but most answers are about loops or input errors, not about double-running on Windows.

Thanks!
