习题1
判断用户的键盘输入内容：
- 如果都是数字，则将该数字扩大10倍，然后打印显示
- 如果是字母，则在其后面增加"@python"后打印显示
- 其他情况则将输入的内容按原样显示
user_input = input(‘input something:‘) if user_input.isdigit(): n = float(user_input) print(n * 10) elif user_input.isalpha(): print(user_input + "@python") else: print(user_input)
习题2
有字符串：Life is short You need python
- 显示每个单词大写和小写两种状态
- 统计每个单词的长度
s = "Life is short You need python" for word in s.split(): print(word, ‘: ‘, word.lower(), ", ", word.upper(), ‘, ‘, len(word))
习题3
写一个猜数游戏程序
- 计算机随机生成一个100以内的正整数
- 用户通过键盘输入数字，猜测所生成的随机数
- 对用户的输入次数不进行限制
import random ran = random.randint(0,100) print(ran) switch = True guess = 0 while switch: inp = int(input("请输入您要猜测的数字：")) guess += 1 if inp == ran: print("恭喜你猜对了!") switch = False print(‘您这次共猜了%s次‘%guess)
习题4
找出列表[2,4,-7,19,-2,-1.45]小于零的数
某学生考试成绩：{‘python‘:89, ‘java‘:58, ‘physics‘:65, ‘math‘:49, ‘Chinese‘:78},找出大于各科目平均分的学科
计算1到99(含)的整数平方的和
>>> lst = [2, 4, -7, 19, -2, -1.45] >>> [i for i in lst if i<0] [-7, -2, -1.45] >>> d = {‘python‘:89, ‘java‘:58, ‘physics‘:65, ‘math‘:49, ‘Chinese‘:78} >>> scores = d.values() >>> mean = sum(scores) / len(scores) >>> mean 67.8 >>> {k:v for k,v in d.items() if v>mean} >>> {k:v for k,v in d.items() if v>mean} {‘python‘: 89, ‘Chinese‘: 78} >>> [i**2 for i in range(1, 100)] [1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900, 961, 1024, 1089, 1156, 1225, 1296, 1369, 1444, 1521, 1600, 1681, 1764, 1849, 1936, 2025, 2116, 2209, 2304, 2401, 2500, 2601, 2704, 2809, 2916, 3025, 3136, 3249, 3364, 3481, 3600, 3721, 3844, 3969, 4096, 4225, 4356, 4489, 4624, 4761, 4900, 5041, 5184, 5329, 5476, 5625, 5776, 5929, 6084, 6241, 6400, 6561, 6724, 6889, 7056, 7225, 7396, 7569, 7744, 7921, 8100, 8281, 8464, 8649, 8836, 9025, 9216, 9409, 9604, 9801]
