我们为python包装了一组c++类。在python中导入其中一个类时,我们将得到以下错误消息:
File ".../myobjects.py", line 176, in <module>
class RT(_object):
File ".../myobjects.py", line 187, in RT
\__swig_destroy__ = _myobjects.delete_RT
AttributeError: 'module' object has no attribute 'delete_RT'

我试图打开一个源图像,读取它的框架,并将它们附加到一个新的图像对象中。它工作到一定程度,然后我收到一个TypeError。“源图像”是一个现有的TIFF,然后是一组我已经验证并转换为TIFF的文档。
from PIL import Image, ImageSequence, TiffImagePlugin
def insert_into_tiff(image_source_path, passed_images, delete_file=False, delete_converted=True):
# create a temporary image to hold all ensui
我有一个java应用程序,它创建一个线程,它将调用Process.exec来启动python程序。但是,当我退出程序时,java线程将停止,但我的python进程继续运行。当我停止执行java文件时,有没有一种方法来停止python进程?
下面是代码的一个片段,它启动新线程,然后启动python脚本的执行。
MyRunnable myRun = new MyRunnable();
Thread myThread = new Thread(myRun);
myThread.start();
myRunable.java类如下所示
public class myRunnable implement
我正在尝试从Java调用python脚本。Python版本为2.7.8
// set up the command and parameter
String pythonScriptPath = "C://Python27//ArcGIS10.3//helloPython.py";
String[] cmd = new String[2];
cmd[0] = "python";
cmd[1] = pythonScriptPath;
// create runtime to execute external com
我有一个csv文件,数据如下:
Text Value

我有一个JSON文件的以下部分: [{"Date":"2020-02-17","Rt_low":0.5,"Rt_avg":1.93,"Rt_up":4,"population":"hosp"},{"Date":"2020-02-18","Rt_low":0,"Rt_avg":1.74,"Rt_up":4,"population":"hosp"}] 我想在Python Pa
使用具有以下内容的虚拟文件(streamt.txt):
andrew I hate mondays.

我正在尝试用Python创建一个虚拟环境,但是无论我重新安装多少次python-setuptools和pip,我总是得到一个错误。
我的电脑运行的是Windows 8,而我使用的是Python 3.3。
E:\Documents\proj>virtualenv venv --distribute

我正在Python上使用Rotten Tomatoes,并且我试图获得我正在搜索的所有电影的列表,但是当我执行请求时,我只能显示一个结果(因为:电影),我如何才能得到所有的电影作为结果?
这是我的密码:
from rottentomatoes import RT
RT_KEY = 'XXXXXXXXX'
rt = RT(RT_KEY)
movie = raw_input('Enter the movie name: ')
fl = rt.search(movie, page_limit= 5)
title = fl['title'] #In or
如何在python脚本上打印postgres的存储过程?
postgres中的存储过程示例如下:
create or replace function checktime() returns void
language plpgsql
as $$
DECLARE timestart TIMESTAMP;
FOR id from rt LOOP
SELECT timeofday() into timestart;
RAISE NOTICE 'Time now : %', timestart;
END LOOP;
END;
$$
;
在python中,我
i = ["booking id is 5677","AE345RT is your booking id","booking id-3456","Booking id - ER3561"]
我必须从这些字符串中提取预订in,我目前在python3工作。产出如下:
5677,AE345RT,3456和ER3561
当我尝试pip install涉及C编译的东西(特别是Pillow)时,我得到一个奇怪的错误:

如何使用rt函数,正如我所理解的,引导和尾随下划线__and__()可用于本地python对象,或者您不能在特定情况下自定义行为。用户如何利用它的优势。在下面的代码中,我可以使用这个函数吗?
class A(object):
def __rt__(self,r):
return "Yes special functions"
a=A()
print dir(a)
print a.rt('1') # AttributeError: 'A' object has no attribute 'rt'
但

这是有史以来最奇怪的错误- Python os.listdir()对每个目录都会失败:

我有两个名单
1.包含Keys
2.包含Keys+Values
现在,我必须创建一个字典,它将过滤掉键,并在下一个键到达列表之前插入所有值。
示例:
List 1: ['a','ef','ddw','b','rf','re','rt','c','dc']
List 2: ['a','b','c']
Dictionary that I want to create: {
'a':['
