 4、单行打印

 5、账号密码,输入框:

一种:

print(username,password)

 

 二种:

name = input("name:")
job = input("job:")

info = '''
----- info of %s -------
name:%s
job:%s
''' % (name,name,job)
print(info)

 

 #str转换成int
age = int(input("age:"))

#打印字符类型,把age转为字符串str(age)
print(type(age),type(str(age)))


#d:整数、f:小数
age:%s
