1. 使用while循环输入 1 2 3 4 5 6 8 9 10

 0
while count < 10:
    count += 1
    if count == 7:
        print(' ')
    else:
        print(c

01

count = 0
while count < 10:
    count += 1
    if count == 7:
        continue
    print(count)

02

2. 输出 1-100 内的所有奇数

count = 1
while count < 101:
    print(count)
    count += 2

01

count = 1
while count < 101:
    if count % 2 == 1:
        print(count)
    count += 1

02

3. 求1-2+3-4+5 ... -99的所有数的和

m = 0
count = 1
while count < 100:
    if count % 2 == 0:
        sum = sum - count
    else:
        sum = sum + count
    count += 1
print(sum)

01

3.1 计算 1 - 2 + 3 ... + 99 中除了88以外所有数的总和

i=1
sum=0
while i <100:
    if i==88:
        i += 1
        continue
    if i%2!=0:
        sum=sum+i
    else:
        sum=sum-i
    i += 1
print(sum)

01

i=0
j=-1
sum=0
while i<99:
    i=i+1
    if i==88:
        continue
    else:
        j = -j
        sum=sum+i*j

print(sum)

4. 用户登陆（三次机会）

i = 0
while i < 3:
    username = input('请输入账号：')
    password = input('请输入密码：')
    if username == 'zss' and password == '123':
        print('登录成功')
        break
    else:
        print('登录失败请重新登录')
    i += 1
else:
    print("滚蛋吧")

基础版

username = "zss"
password = "123"
i = 3
while i > 0:
    zh = input("请输入你的账号:")
    i -= 1
    if zh == username:
        mm = input("请输入你的密码:")
        if mm == password:
            print("验证成功.正在登陆......")
            print('''恭喜你登陆成功!
            欢迎用户进入
            用户名 :%s
            密码   :%s
            '''%(zh,mm))
            break
        else:
            if i == 0:
                print("你的机会已经没了!game over 下次见!")
                answer = input('再试试？Y or N')
                if answer == 'Y':
                    i = 3
            print("密码错误,请重新输入")
            print("你还有"+str(i)+"次机会")
    else:
        print("请输入正确的用户名!")
        if i == 0:
            print("你的机会已经没了!")
            answer = input('再试试？Y or N')
            if answer == 'Y':
                i = 3
        print("你还有" + str(i) + "次机会")
else:
    print('你TM要不要脸')

5. 格式化输出

name = input('请输入姓名:')
age = input('请输入年龄:')
job = input('请输入工作:')
hobbie = input('你的爱好:')

msg = '''------------ info of %s -----------
Name  : %s
Age   : %d
job   : %s
Hobbie: %s
------------- end -----------------''' %(name,name,int(age),job,hobbie)
print(msg)

01

name = input('请输入姓名:')
age = input('请输入年龄:')
job = input('请输入工作:')
hobbie = input('你的爱好:')

msg = '''------------ info of {0} -----------
Name  : {0}
Age   : {1}
job   : {2}
Hobbie: {3}
------------- end -----------------''' .format(name,int(age),job,hobbie)
print(msg)

 6. 使用while和for循环分别打印字符串s=’asdfer’中每个元素

s = 'fkld'
for i in s:
    print(i)

index = 0
while 1:
    print(s[index])
    index += 1
    if index == len(s):
        break

7. 任意输入一串文字+数字 统计出来数字的个数

s = input("请输入：")  # '1234324324fdsaf1fdsaf12'
count = 0
for i in s:
    if i.isdigit():
        count += 1
print(count)

8. 如用户输入：5+9或5+ 9或5 + 9，然后进行分割再进行计算

content=input('>>>').strip()
con1=content.split('+')
num=0
for i in con1:
    num+=int(i)
print(num)

content=input('>>>').strip()
index = content.find("+")
a = int(content[0:index])
b = int(content[index+1:])
print(a + b)
