Tips

  • equivalent of the C ternary operator ?: (bool ? restrue : 'resfalse), use a tuple

<source lang="py"> (resfalse,restrue)[bool] </source>

  • adding a path to a directory containing your module files

<source lang="py"> import sys sys.path += [ "/home/username/bin/Python" ] </source>

  • test whether a string has only digits or letters

<source lang="py"> str = '1321' str.isdigit() # returns True/False str.isalpha() # returns True/False </source>

  • Nested for loops in a single line:

<source lang="py"> for n,m in [ (n,m) for n in range(10) for m in range(2) ]:

   print n,m

</source>
