python——生成器函数

由 爱⌒轻易说出口 提交于 2019-11-26 16:55:56
1.生成器 生成器的本质就是迭代器 生成器的特点和迭代器一样，取值方式和迭代器一样（__next__()，）。 send():的作用是给上一个yield传值 生成器一般由生成器函数或者生成器表达式来创建 其实就是手写的迭代器 生成器函数 和普通函数写法没有区别，里面有yield的函数就是生成器函数。 生成器函数在执行的时候，默认不会执行函数体，而是返回生成器， 通过生成器的__next__()分段执行这个函数 send():的作用是给上一个yield传值，不能在开头使用，因为没有上一个yield，最后一个yield也不可以用send，因为会报错停止生成器。 yield　　 yield：相当于return，可以返回数据。但是yield不会彻底中断函数。分段执行 函数中如果有yield，这个函数就是生成器函数。 生成器函数名（） 获取的是生成器。这个时候不执行函数。 def func(): 　　print('执行到第一yield，下面是返回值') 　　yield 1　　 # return和yield都可以返回数据 　　print('执行第一个yield不会打印这个条，再次使用gen.__next__()调用才会打印，下面是返回值') 　　yield 2 gen = func() # 拿到生成器，不会执行函数 gen.__next__() # 执行函数，执行到下一个yield gen._

Python Socket Send Buffer Vs. Str

由 梦想的初衷 提交于 2019-11-26 16:45:11
问题 I am trying to get a basic server (copied from Beginning Python) to send a str. The error: c.send( "XXX" ) TypeError: must be bytes or buffer, not str It seems to work when pickling an object. All of the examples I found, seem to be able to send a string no problem. Any help would be appreciated, Stephen import socket import pickle s = socket.socket() host = socket.gethostname() port = 80 s.bind((host, port)) s.listen(5) while True: c, addr = s.accept() print( "Got Connection From ", addr )
