Input 无法从异步IO中的标准输入读取文件
我已经编写了一个在asyncio上工作的代码。在这段代码中,我必须使用Input 无法从异步IO中的标准输入读取文件,input,python-3.6,python-asyncio,Input,Python 3.6,Python Asyncio,我已经编写了一个在asyncio上工作的代码。在这段代码中,我必须使用/check.py
/check.py
我能够从终端提供输入。正常情况下,它工作正常。
但它不适用于从标准输入读取文件中的数据
#!/usr/bin/env python3.6
import asyncio
from aioconsole import ainput
async def read_input():
while True:
inp = await ainput()
print('got ' + inp)
if (__name__ == "__main__"):
asyncio.get_event_loop().run_until_complete(read_input())
通常它的工作原理是
$ ./check.py
4
got 4
5
got 5
但是,当我直接从文件中读取时,我面对这个日志:
$ ./check.py < test/test_case
Traceback (most recent call last):

$./check.py
无法理解为什么它的行为有所不同?
我想使用协同程序读取一个类似于/check.py
的文件。这是一个已在中修复的文件
只需运行以下命令即可获得最新版本:
$ pip3 install -U aioconsole
这看起来很像一个bug:)你能在上报告吗?当然我会发布,谢谢:)现在我无法获得最新版本。我正在使用python3.6和pip3.6。我正在完成“需求已经是最新的:aioconsole in/usr/local/lib/python3.6/dist-packages(0.1.8)”的工作。命令已成功运行:)更改需要一些时间才能生效:)
