#+号用法

'are you'+'ok'

#面向对象模板拼接
from string import Template
s = Template('${s1} ${s2}!')
print(s.safe_substitute(s1='Hello',s2='world'))

#join()拼接方式
str_list = ['Hello','wordl']
str_join1 = ''.join(str_list)
str_join2 = '-'.join(str_list)
print(str_join1)
print(str_join2)

#f-string（3.6后新功能）
name = 'world'
myname = 'python_cat'
words = f'Hello {name}. My name is {myname}.'
