我试图实时获得一个进程的输出,同时将它保存到一个变量中,我试着查看其他堆栈溢出问题,但是我在StreamReader myStreamReader = myProcess.StandardOutput行中得到了一个InvalidOperationException错误,我遗漏了什么?如何修复它?

我正在使用Pycharm和Python3.4开发Django 1.8.4项目。
我试图在shell上创建一个Model对象来测试一些内容,并在执行这一行时:
song1 = Cancion.objects.create(nombre="City Lights",
audio_file=File(open("C:\\Users\\pablo\\Desktop\\Music\\Brian Culbertson - Another Long Night Out (2014)\\01 - City Lights (
所以我运行了brew doctor,结果如下:
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

下面是供您参考的终端日志

我编写了一个简单的Python3程序,如下所示:
import sys
input = sys.stdin.read()
tokens = input.split()
print (tokens)
a = int(tokens[0])
b = int(tokens[1])
if ((a + b)> 18):
print ("Input numbers should be between 0 and 9")
else:
print(a + b)
但在像下面这样运行时:

我有以下setup.py文件:
import setuptools
import setuptools.config
_CONFIG = setuptools.config.read_configuration('setup.cfg')
setuptools.setup(
**_CONFIG
)
...and setup.cfg文件:
[metadata]
name = Example
version = 1.0.0
author = First Last
author_email = first.last@example.com

我刚刚开始学习hadoop,并且我已经编写了一个map reduce作业,当我在hortonworks沙箱上运行该作业时,我得到如下错误:

所以这里:
glove_path = './embeddings/glove_{}_{}.pkl'.format(dataset,mode)
if(os.path.isfile(glove_path)):
print("Reusing glove dictionary to save time")
#with open(glove_path,'r') as f:
with open(glove_path, 'rb') as f: #python 3 for pickle byte s
我想我有点误会了。我制作了一个简单的python测试文件,以了解权限如何影响python文件的使用。我这么做是为了能够回答64位ubuntu12.04蟒无法运行现有python文件
SetUp
我制作了一个包含内容的test.py文件
print 'I am working'
测试用例1
ls -al test.py
-rw-r--r-- 1 joey joey 25 Dec 24 11:11 test.py
python test.py
I am working
尽管我没有执行chmod +x test.py,但是python为什么要执行这个文件呢?
测试用例2
chmod
我正在为初学者阅读关于python的教程,在某个时候,作者定义了一些处理文件的方法。我的怀疑与内存管理和文件数组有关。
#open a file for reading
file = open(filename, 'r')
#this turns the file into an array.
lines = file.readlines() `
Python足够聪明来检查文件大小吗?如果文件有大约1GB的数据,会发生什么?Python会将整个文件抛到内存(数组)中吗?或者这是一个懒惰的操作,就像C/C++一样!
提前谢谢。
我正在读一个文本文件。我一直用python2做得很好,但我决定用python3来运行我的代码。 我用来读取文本文件的代码是: neg_words = []
with open('negative-words.txt', 'r') as f:
for word in f:
neg_words.append(word) 当我在python 3上运行这段代码时,我得到了以下错误: UnicodeDecodeError Traceback (most recent call last)
