At the top where it says “otherwise, you can get it installed with the command “sudo apt-install python3-rpi.gpio”, that needs to be sudo apt-get install or sudo apt install, for those that are new to linux 🙂

Ok, please remove this part from the print statement:
+ ” “, end=’\r’

At the end, it should work as required

It prints the distance reading for a couple of seconds ( 4-5 ) seconds, then stops. So it’s not infinite anymore.
Now I need to figure out how to get 10 readings, each one on a new line, so that I can print that to a text file.The 10 readings fluctuate, but to fast to capture all ten different ones.
Any input would be most welcome.

Ah, ok.
The print statement must stay in a different row from while one. It has also to be indented compared to the while line.
The x+=1 line has to be indented as the print statement

The ouput is :
Distance: 287.5 – and this fluctuates, but hasn’t stopped.

The pastebin is about the new code.
I didn’t understand if it stopped or not after the 10 runnings. Please can you share the print output?

Here is what I have :https://pastebin.com/FvTTCXcX

…and remove the “while True:” line from your code
