1.% :占位符
%s:字符串占位符;既可以接收字符串,也可以接受数值
%d:数值占位符;只能接受数值。
案例:

name = input("your name:")
age = input("your age:")
ads = input("your ads:")
print("my name is %s,my age is %s,my ads is %s" % (name,age,ads))
2)
info = '''
------------ info of %s -----------
Name:%s

'''% ('sean','sean','male','18','Teacher')
print(info)
3)
print("my name is %s,my age %s"%("sean","18岁"))
4)
name = '王家卫'
age = 31
adds = 'HK'
print('Hello Everyone,my name is {},my age is {},my adds is {}'.format(name,age,adds))
# fromat前为英文状态下的句号,而非逗号,与%占位符不同 ,%则无需标点符号
