I warmly recommend downloading Peter Norvig's Python utilities file (http://aima.cs.berkeley.edu/python/utils.py) and putting it on your Python path. (E.g., in bash, put a line like
export PYTHONPATH="/path/to/utilities_directory" in your .bashrc file.) The utils.py file defines many useful functions, including the ones you want: # def every(predicate, seq): # """True if every element of seq satisfies predicate. # Ex: every(callable, [min, max]) ==> 1; every(callable, [min, 3]) ==> 0 # """ # for x in seq: # if not predicate(x): return False # return True # # def some(predicate, seq): # """If some element x of seq satisfies predicate(x), return predicate(x). # Ex: some(callable, [min, 3]) ==> 1; some(callable, [2, 3]) ==> 0 # """ # for x in seq: # px = predicate(x) # if px: return px # return False Michael -- Michael D.
