Python 2.5 is relatively recent and not supported everywhere yet, so it’s important to understand the behavior of both Python 2.5 and earlier versions.
This quiz is cited from here.
- (a) What number does the following code print?
adders = [] for i in range(0, 100): adders.append(lambda x: x+i) print adders[17](42)(b) What about the following similar-looking code?
adders = [lambda x: x+i for i in range(0, 100)] print adders[17](42)
- (pre-Python 2.5 only) What does the following code print? Partial credit for approximately correct answers. (Hint: the function that exits a program is called sys.exit.)
try: exit(0) except Exception, e: print e - What number does the following code print?
units = [1, 2] tens = [10, 20] nums = (a + b for a in units for b in tens) units = [3, 4] tens = [30, 40] print nums.next()
- Which of these lines produce the same output?
print "word" in [] == False print ("word" in []) == False print "word" in ([] == False)
