Tips
- equivalent of the C ternary operator ?: (bool ? restrue : 'resfalse), use a tuple
(resfalse,restrue)[bool]
- adding a path to a directory containing your module files
import sys sys.path += [ "/home/username/bin/Python" ]
- test whether a string has only digits or letters
str = '1321' str.isdigit() # returns True/False str.isalpha() # returns True/False
- Nested for loops in a single line:
for n,m in [ (n,m) for n in range(10) for m in range(2) ]: print n,m
