我对python编程很陌生,我想尝试一个简单的文本冒险游戏,但我立即偶然发现了一个障碍.

class userInterface:
    def __init__(self, roomID, roomDesc, dirDesc, itemDesc):
        self.roomID = roomID
        self.roomDesc = roomDesc
        self.dirDesc = dirDesc
        self.itemDesc = itemDesc

    def displayRoom(self): #Displays the room description
        print(self.roomDesc)

    def displayDir(self): #Displays available directions
        L1 = self.dirDesc.keys()
        L2 = ""
        for i in L1:
                L2 += str(i) + " "
        print("You can go: " + L2)

    def displayItems(self): #Displays any items of interest
        print("Interesting items: " + str(self.itemDesc))

    def displayAll(self, num): #Displays all of the above
        num.displayRoom()
        num.displayDir()
        num.displayItems()

    def playerMovement(self): …

我对python有点新,但熟悉OOP.我正在尝试使用PyGame编写游戏.基本上,我的目标是每隔几秒钟渲染一次树木,并将树木移动到整个屏幕上.

所以这是我的代码:

from collections import deque
import pygame,random,sys

pygame.init()
size = 800,600
screen = pygame.display.set_mode(size)

class tree:
    def __init__(self):
            self.img = pygame.image.load("tree.png")
            self.rect = self.img.get_rect()
    def render(self):
            screen.blit(self.img,self.rect)
    def move(self,x,y):
            self.rect = self.rect.move(x,y)

#creating a queue of trees
trees = deque()

#appending the first tree on to the queue 
trees.append(tree())


while 1:


    for event in pygame.event.get():
            if event.type == pygame.QUIT: sys.exit()

    #appending tree() to trees queue every 300 ms
    if pygame.time.get_ticks() % 300 == 0:
            trees.append(tree())

    #rendering and moving all …

如何CAP_PROP_FRAME_COUNT从python中的opencv 访问？我试过这个:

import cv2
cap = cv2.VideoCapture('myvideo.avi')
frames_count, fps, width, height = cap.get(cv2.CAP_PROP_FRAME_COUNT), cap.get(cv2.CAP_PROP_FPS), cap.get(cv2.CAP_PROP_FRAME_WIDTH), cap.get(cv2.CAP_PROP_FRAME_HEIGHT)

还有这个:

import cv2
import cv
cap = cv2.VideoCapture('myvideo.avi')
frames_count, fps, width, height = cap.get(cv.CAP_PROP_FRAME_COUNT), cap.get(cv.CAP_PROP_FPS), cap.get(cv.CAP_PROP_FRAME_WIDTH), cap.get(cv.CAP_PROP_FRAME_HEIGHT)

还有这个:

import cv2
cap = cv2.VideoCapture('myvideo.avi')
frames_count, fps, width, height = cap.get(cv2.cv.CAP_PROP_FRAME_COUNT), cap.get(cv2.cv.CAP_PROP_FPS), cap.get(cv2.cv.CAP_PROP_FRAME_WIDTH), cap.get(cv2.cv.CAP_PROP_FRAME_HEIGHT)

但是我收到了这个错误:

AttributeError: 'module' object has no attribute 'CAP_PROP_FRAME_COUNT'

我正在使用python 2.7.5和OpenCV 2.4.9.

我试图将共享秘密传递给子进程.在Linux环境中,这可行.在Windows环境中,孩子不会收到共享密钥.下面的三个文件是我正在尝试做的一个简单示例:

main.py

import multiprocessing
import module1
import module2

if __name__ == "__main__":
    module1.init()
    process = multiprocessing.Process(target=module2.start)
    process.start()
    process.join()

module1.py

import ctypes
import multiprocessing

x = None

def init():
    global x
    x = multiprocessing.Value(ctypes.c_wchar_p, "asdf")

module2.py

import module1

def start():
    print(module1.x.value)

在Ubuntu 14.04环境中,在Python 3.5上,我收到以下输出:

$ python3 main.py
asdf

在CentOS 7环境中,我收到以下输出:

$ python3 main.py
asdf

在Windows 10上使用Windows子系统Linux(在创建者更新之前和之后,所以Ubuntu 14.04和16.04)我得到以下输出:

$ python3 main.py
asdf

但是,在Windows 7和Windows 10环境中,使用3.5或3.6,我得到的AttributeError不是上面的输出:

Process Process-1:

我收到错误 AttributeError: 'Response' object has no attribute 'get' 对于我编写的以下代码

def convert_json(self,bucket,userid,imgfilename,field,i):

    bucketName = bucket
    link = "users_"+str(userid)+'/'+imgfilename
    c = S3Connection(self.AWS_ACCESS_KEY_ID,self.AWS_ACCESS_KEY_SECRET)
    p = c.generate_url(expires_in=long(7200),method='GET',bucket=bucketName,key=link,query_auth=True,force_http=False)  
    post_url = "http://someurl"
    wrapper = {"filename":p}
    try:
        response = requests.post(post_url, json=wrapper)
        print response
        if response.status_code == 200:
            text = response.get('description', [])
        else:
            text = []
    except Exception:
        if response.status_code == 200:
            text = response.get('description', [])
        else:
            text = []
    return text

我看过这篇关于如何从django运行python脚本的帖子:http: //www.djangotutsme.com/how-to-run-python-script-from-django/

问题:我一直在使用Google的Python脚本示例将apk上传到Play商店并获取通过我的帐户发布的应用列表(list_apks.py和upload_apk.py).然而最近它开始打破.我试图通过这样做来更新类似的软件包google-api-python-client,但它没有帮助.oath2clientpip install --update packagename

日志:

这个如果在列出apk的时候:

如您所见,我在cmd(win 10)中运行此代码."import tensorflow.contrib"和"import tensorflow.python"都可以,但命令"tensorflow.contrib"和"tensorflow.python"是不同的.一个返回一个目录,另一个返回AttributeError.

有没有人知道为什么？
