python3 conversion: fix tabs and spaces inconsistency

Without that fix we have:
  $ python3 pySim-read.py
    File "pySim-read.py", line 135
      try:
         ^
  TabError: inconsistent use of tabs and spaces in indentation

The following command was used to do the conversion:
  sed 's#        #\t#g' -i $(find -name "*.py")

Then the remaining spaces spotted during the review were
addressed manually.
