while 循环 格式化 逻辑运算

#1、使用while循环输入 1 2 3 4 5 6 8 9 10
'''
count = 0
while count < 10:
    count += 1  # count = count + 1
    if count == 7:
        print(' ')
    else:
        print(count)

count = 0
while count < 10:
    count += 1  # count = count + 1
    if count == 7:
        continue
    print(count)
'''
#3、输出 1-100 内的所有奇数
#方法一：
# count = 1
# while count < 101:
#     print(count)
#     count += 2
#方法二：
# count = 1
# while count < 101:
#     if count % 2 == 1:
#         print(count)
#     count += 1

#5、求1-2+3-4+5 ... 99的所有数的和
# sum = 0
# count = 1
# while count < 100:
#     if count % 2 == 0:
#         sum = sum - count
#     else:
#         sum = sum + count
#     count += 1
# print(sum)

#6、用户登陆（三次机会重试）
#input 心中有账号，密码 while

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

# 算法 ：  () >  not > and> or    非   或   与  优先级
#
# print(3>4 or 4<3 and 1==1)    # f
#
# print(1 < 2 and 3 < 4 or 1>2)  # t
#
# print(2 > 1 and 3 < 4 or 4 > 5 and 2 < 1)   # T
#
# print(1 > 2 and 3 < 4 or 4 > 5 and 2 > 1 or 9 < 8)  # F
#
# print(1 > 1 and 3 < 4 or 4 > 5 and 2 > 1 and 9 > 8 or 7 < 6)   #  F
#
# print(not 2 > 1 and 3 < 4 or 4 > 5 and 2 > 1 and 9 > 8 or 7 < 6)  # F



# int ===> bool 非零转换布尔值是  True 零 就是 false
print(bool(4))
print(bool(-4))
print(bool(0))
# bool===> int  布尔转数字
print(int (True))
print(int (False))
# x or y  x 非零，则返回左边x
# print(1 or 2 )   # 1
# print(3 or 2)    #3
# print(0 or 3)    #  3
# print(0 or 100)   # 100

# x and y    和 or 相反

print(1 and 2 )   # 2
print(3 and 2)    #2
print(0 and 3)    #  0
print(0 and 100)   # 0
#
# # 练习：
#
# print(2 or 4 or 9 or 100 or 6)   # 2
#
# print( 0 or 5 and 4 or 5 )   # 优先级   先  5 and4  返回4   在 0 or 4  or  5   输出4
#
# print(1>2 and 3 or 4 and 3<2)    # *****
#
#
#
# # 用户交互
# name=input('请输入你的名字==》')
# age=input ('请输入你的年龄==》')
# print('我 的名字是'+name,'我的年龄是' +age )   # 语法要求带个加号 +    字符拼接上

if判断
print(111)
if True:
    print(222)
print(4444)

if 3>2:
    print('玩')
else:
    print('不玩')

if 3>4:
    print('玩')
else:
    print('不玩')

多选
num=input('请输入你猜的数字')    #  input 输入的是字符串  所以  1  加引号   也可用str()转化
#
# if num==str(1):
#     print('吃饭')
# elif num=='2':
#     print('玩去')
# elif num=='3':
#     print('逛街')
# else:
#     print('都猜错了')

while循环

print(222)
while True:
    print(444)
    print(555)
print(777)

# 无限循环     终止循环  就要改变条件
count=1
flag=True   #  标志位
while flag:
    print(count)  # 算出count = 1
    count+=1  #  count = count+1   算出结果 2 覆盖掉了  1
    if count>100:
        flag=False

count= 1
while count<=100:
    print(count)
    count+=1

count=1
while True:
    print(count)
    count+=1
    if count>10 :break    #break 是程序终止


count=1
while count<=10:
    print(count)
    count+=1

    # if count>10 :break    #break 是程序终止

# 格式化输出

# name=input('请输入你的名字')
# age=input('请输入你的年龄')
# height=input('请输入你的身高')
# mag=(name,age,height)
# print(mag)
