数字和字符串类型
对字符串的操作
有如下变量name = " aleX"
,请按照要求实现每个功能:
1. 移除 name 变量对应的值两边的空格,并输出处理结果
2. 判断 name 变量对应的值是否以 "al" 开头,并输出结果
3. 判断 name 变量对应的值是否以 "X" 结尾,并输出结果
4. 将 name 变量对应的值中的 “l” 替换为 “p”,并输出结果
5. 将 name 变量对应的值根据 “l” 分割,并输出结果。
6. 将 name 变量对应的值变大写,并输出结果
7. 将 name 变量对应的值变小写,并输出结果
8. 请输出 name 变量对应的值的第 2 个字符?
9. 请输出 name 变量对应的值的前 3 个字符?
10. 请输出 name 变量对应的值的后 2 个字符?
11. 请输出 name 变量对应的值中 “e” 所在索引位置?
12. 获取子序列,去掉最后一个字符。如: oldboy 则获取 oldbo
name = " aleX"
print(name.strip())
aleX
print(name.startswith('al'))
False
print(name.endswith('X'))
print(name.replace('l','p'))
print(name.split('l'))
print(name.upper())
print(name.lower())
print(name[1])
print(name[:3])
print(name[-2:])
print(name.find('e'))
print(name.rstrip('X'))
True
apeX
[' a', 'eX']
ALEX

a
al
eX

编年龄游戏
- 编写猜年龄游戏,有以下要求:
- 可能会有用户会在输入年龄之后不小心输入空格,如18 ,请做处理
- 可能会有用户会恶意输入导致程序报错,如
逗你玩呀
,请做处理 - 如果用户3次没有猜对,可以选择继续玩或退出(自定义退出条件)
- 如果用户猜对了,可以在以下奖品中选择两件奖品(一次只能选择一件奖品):
{0:'toy_car',1:'doll',2:'puzzle'}
- 用户选择奖品后退出程序,用户也可以不选择奖品直接退出程序。
real_age = 18
count =1
while count<=3:
age = input("please enter the age").strip()
if age.isdigit():
if int(age) == 18:
print('congratulations!')
for i in range(2):
prize_dict = {0:'toy_car',1:'doll',2:'puzzle'}
print(f'please choose one of these gifts: {prize_dict}')
prize = input('please enter the num:')
if prize == 'N' or prize == 'n':
count = 5
break
print(f'Congratulations, you have received this gift,the gift is {prize_dict[int(prize)]}')
break
else:
print("sorry,guess wrong")
if int(age) >18:
print("sorry,guess older")
else:
print("sorry,guess younger")
else:
print(f'your age is {age}?')
count +=1
if count == 4:
chance = input("please choose you should continue play this game<<<")
if chance == 'Y'or chance =='y':
count =1
elif chance == 'N'or chance =='n':
break
else :
print('please make sure your input is correct')
please enter the age18
congratulations!
please choose one of these gifts: {0: 'toy_car', 1: 'doll', 2: 'puzzle'}
please enter the num:0
Congratulations, you have received this gift,the gift is toy_car
please choose one of these gifts: {0: 'toy_car', 1: 'doll', 2: 'puzzle'}
please enter the num:1
Congratulations, you have received this gift,the gift is doll
