1.有变量name = "aleX leNb",完成以下操作
name = "aleX leNb"
# 1)移除name变量对应的两边的空格
s1 = name.strip(' ')
# 2)移除name变量左边‘al’
s2 = name[2:]
s3 = name.lstrip('al')
# 3)移除name变量右边‘Nb’
s4 = name[:7]
s5 = name.rstrip('Nb')
# 4)移除name变量开头的‘a’和结尾的‘b’
s6 = name[1:-1]
# 5)判断变量是否以‘al’开头
s7 = name.startswith('al')
# 6)将name变量对应的所有的‘l’转换为‘p’
s8 = name.replace('l','p')
# 7)将name变量对应的所有的‘l’分割
s9 = name.split('l')
# 8)将name变量值变大写
s10 = name.upper()
# 8)将name变量值变小
s11= name.lower()
# 9)将name变量首字母大写
s12 = name.capitalize()
# 10)判断name变量‘T’出现几次
s13 = name.find('T')
# 11)从变量name中找到‘N’所在的索引，不在则报错
s14 = name.index('N')
2.使用while和for循环分别打印字符串s="asdfer"
s = "asdfer"
i = 0
while i < len(s):
print(s[i])
i = i+1
for i in s :
print(i)
3.实现一个整数加法计算器 如：content=input() 如果用户输入5+9或5+ 9或者 5 + 9然后进行分割运算
content = input("请输入内容")
s = content.split('+')
s1 = s[0]
s2 = s[1]
s1 = int(s1.strip(' '))
s2 = int(s2.strip(' '))
print(s1+s2)
4.计算用户输入的内容有几个整数 如：content=input()
content = input("请输入内容")
count = 0
for i in content:
if i > '0' and i < '9':
count += 1
print(count)
