本文實例講述了Python實現的簡單算術游戲。分享給大家供大家參考。具體實現方法如下：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 #!/usr/bin/env python from operator import add, sub from random import randint, choice ops = {'+': add, '-':sub} #定義一個字典 MAXTRIES = 2 def doprob(): op = choice('+-') #用choice從'+-'中隨意選擇操作符 nums = [randint(1,10) for i in range(2)] #用randint(1,10)隨機生成一個1到10的數,隨機兩次使用range(2) nums.sort(reverse=True) #按升序排序 ans = ops[op](*nums) #利用函數 pr = '%d %s %d = ' % (nums[0], op, nums[1]) oops = 0 #oops用來計算failure測試,當三次時自動給出答案 while True: try: if int(raw_input(pr)) == ans: print 'correct' break if oops == MAXTRIES: print 'answern %s%d' % (pr, ans) break else: print 'incorrect... try again' oops += 1 except (KeyboardInterrupt, EOFError, ValueError): print 'invalid ipnut... try again' def main(): while True: doprob() try: opt = raw_input('Again? [y]').lower() if opt and opt[0] == 'n': break except (KeyboardInterrupt, EOFError): break if __name__ == '__main__': main()運行結果如下：
?
1 2 3 4 5 6 7 8 9 8 - 1 = 7 correct Again? [y]y 7 - 1 = 6 correct Again? [y]y 9 + 4 = 0 incorrect... try again 9 + 4 =希望本文所述對大家的Python程序設計有所幫助。
