: : 接龍 :P
: : import os
: : exists = lambda f : (os.path.exists(f) and "exists") or "not exist"
: : print exists('test.py')
: ............... 這樣倒不如直接寫
: print ('not exist', 'exists')[os.path.exists("aaa")]

print "exists" if os.path.exists(f) else "not exist"
都什麼年代了還在用 logic operator？ :p

Python 3.0:
print("exists" if os.path.exists(f) else "not exist")
