This time as an example, let’s try to run helloworld.py file.
helloworld.py contents is just following,

print("Hello World")

Let’s run!
Launch command prompt and input following;

python helloworld.py

1st: input “python”
2nd: input space
3rd: input “the file name”

As a result, “Hello World” is displayed.

If the current directory of command prompt is different from the python file path,
we need to input not only the file name but the file path too as following.

python filepath/helloworld.py

If you feel it’s complicated to input the file path,
you can just drag and drop the file.

Thus common method is following;

– Launch command prompt
– Input “python”
– Input space
– Drag & Drop the file

Have a nice python life!
