I'm not a python expert, but when I google "python print" it tells me that the "f-strings" like

>      print(DEFAULT_PREFIX + f"SCRATCH = {scratch}")
>                                                  ^
> SyntaxError: invalid syntax

are supported only in python 3.6 or later.
Most likely, you must update your python version.

Hello,

I am writing to seek your assistance in testing Example 5 of the tutorial for Raspberry Pi - TaAs.

I have encountered several issues while attempting to run this example. Despite my efforts to resolve them by using both the Wein19, Wein21, and Wein23 versions, the same errors persist:

d
Input file name: Wloop.in
Additional options:
Checking existance of Wloop.in
-- OK
Success
Working directory = /home/halima/Documents/wien19/SRC_BerryPI/BerryPI/tutorials/tutorial5/TaAs
Wilson Loop ---------------------  1 of 91
  File "/home/halima/Documents/wien19/SRC_BerryPI/BerryPI/berrypi", line 184
     print(DEFAULT_PREFIX + f"SCRATCH = {scratch}")
                                                 ^
SyntaxError: invalid syntax
Traceback (most recent call last):
   File "WloopPHI.py", line 267, in <module>
    direction, Data = Solve(WorkingDir, KlistFileName, n, multiplier, S_Band, E_Band, K_Start, K_End)
   File "WloopPHI.py", line 162, in Solve
     with open(berrypiOutFileName, 'r') as read_file:
FileNotFoundError: [Errno 2] No such file or directory: 'TaAs.outputberry'

I would greatly appreciate your guidance and support in troubleshooting and resolving these issues.

Thank you in advance for your assistance.

Cordially,

Safae Benyoussef
