<head>  打印命令   print  
----print  打印命令------
定义变量格式  XXX = ("XXX")
引用格式1:print(XXX)
引用格式2:print(‘输入任何内容加引号‘,XXX)



打印字符类型
print(type(XXX))


实验
name = "Hello World!"
print(name)
print(‘my name is‘,name)
返回结果
Hello World!
my name is Hello World!
------------------------------
</head>
<head>  交互式输入 input
AAA = input("AAA:")
BBB = input("BBB:")
print(AAA,BBB)

</head>
<head>  格式打印
#%s   (全拼string) (验证字符)
#%d       整数             (验证整数)检测验证数据类型 错误则报错
#%f        浮点数    
.format  格式2、3 指定{}中内容=某个变量

---------格式打印1-------------
AAA = ‘111‘
BBB = ‘222‘
CCC = ‘333‘

test = ‘‘‘
%s                                            
%s                                                
%s                                             
‘‘‘%(AAA,BBB,CCC)
print(test)

实验
name = ‘gaoliandi‘
ago = ‘30‘
work = ‘IT‘

info = ‘‘‘
%s
%s
%s
‘‘‘%(name,ago,work)
print(info)

--------格式打印2--------------
AAA = ‘111‘
BBB = ‘222‘
CCC = ‘333‘

test = ‘‘‘
{aaa}
{bbb}
{ccc}
‘‘‘.format(aaa=AAA,
           bbb=BBB,
           ccc=CCC)
print(test)

--------格式打印3--------------
AAA = ‘111‘
BBB = ‘222‘
CCC = ‘333‘

test = ‘‘‘
{0}
{1}
{2}
‘‘‘.format(AAA,BBB,CCC)
print(test)

</head>
<head>  字符转换   int  str
int(XXX) 转化整数
str(XXX) 转化字符

</head>
<head>    利用交互式输入账户密码(加密) 判断账户密码是否正确
笔记
import getpass    调用getpass模块    import加载模块命令
模板 password = getpass.getpass("password:")
if (判断条件,不缩进) 子命令行必须缩进
else: (否则执行条件,不缩进) 子命令行必须缩进

实验
import getpass
_username = "gaoliandi"
_password = "abc123"
username = input("username:")
password = getpass.getpass("password:")

if _username == username and _password == password:
    print(‘Welcone user {name} login...‘.format(name=username))
else:
    print("Invalid username or password!")
