救命！当我让一件事情起作用时，其他事情却不起作用！再次，我相信经验丰富的眼睛很简单，但是我很挣扎！这是我生成清单和清单数据的代码。

#Frame Creation


allframes = []

for n in range (0, (workingframes*archnodes*3)):
    allframes.append(n)

frames = allframes

print frames

我不断收到这个可爱的错误：

AttributeError: 'int' object …

我的代码是:

from random import randrange, choice
from string import ascii_lowercase as lc
from sys import maxsize
from time import ctime

tlds = ('com', 'edu', 'net', 'org', 'gov')

for i in range(randrange(5, 11)):
    dtint = randrange(maxsize)                      
    dtstr = ctime()                                  
    llen = randrange(4, 8)                              
    login = ''.join(choice(lc)for j in range(llen))
    dlen = randrange(llen, 13)                          
    dom = ''.join(choice(lc) for j in range(dlen))
    print('%s::%s@%s.%s::%d-%d-%d' % (dtstr, login,dom, choice(tlds),
                                  dtint, llen, dlen), file='redata.txt')

我想在文本文件中打印结果,但是我收到此错误:

我正在尝试使用set_major_formatter在matplotlib图上格式化yaxis。该图已正确生成，但ax.yaxis.set_major_formatter（）引发了一些奇怪的错误。

格式化程序：

def mjrFormatter(x):
    return "{0:.0f}%".format(x * 100)

使用格式化程序的代码：

 ...
 ax.yaxis.set_major_formatter(mjrFormatter)
 ...

错误：

在python中编写客户端 - 服务器系统时,我在服务器标准输出中遇到了一个奇怪的错误,这不应该发生:

Traceback (most recent call last):
  File "C:\Users\Adam\Drive\DJdaemon\Server\main.py", line 33, in <module>
    ClientThread(csock, addr).start()
AttributeError: 'ClientThread' object has no attribute '_initialized'

我将该行分成多行,而start()导致了错误.

有任何想法吗？这是服务器源代码 - 客户端只是打开并关闭连接:

import socket, threading

class ClientThread(threading.Thread):
    def __init__(self, sock, addr):
        self.sock = sock
        self.addr = addr
    def run(self):
        sock = self.sock
        addr = self.addr

        while True:
            msg = sock.recv(1024).decode()
            if not msg:
                print('Disconnect: ' + addr[0] + ':' + str(addr[1]))
                sock.close()
                return

我最近为此项目安装了pyusb，该项目试图尝试写入USB LED留言板并收到以下错误：

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

我不知道为什么，我检查了pyusb模块文件，它显然有一个名为“ backend”的文件夹，并且里面有正确的文件。

这是我所有的代码：

import usb.core
import usb.util
import sys

backend = usb.backend.libusb01.get_backend(find_library=lambda C: "Users\nabakin\Desktop\libusb-win32-bin-1.2.6.0\lib\msvc_x64")

#LED Display Message device identify
MessageDevice = usb.core.find(idVendor=0x1D34, idProduct=0x0013, backend=backend)

if MessageDevice is None:
    raise ValueError('LED Message Display Device could not be found.')

MessageDevice.set_configuration()





# get an endpoint instance
cfg = MessageDevice.get_active_configuration()
interface_number = cfg[(0,0)].bInterfaceNumber
print interface_number
alternate_settting = usb.control.get_interface(interface_number)
intf = usb.util.find_descriptor(
    cfg, bInterfaceNumber = interface_number,
    bAlternateSetting = alternate_setting
)

ep = usb.util.find_descriptor(
    intf, …

我正在尝试使用同事写的脚本.

这部分脚本工作正常:

xl = pd.ExcelFile(path + WQ_file)
sheet_names = xl.sheet_names

df = pd.read_excel(path + WQ_file, sheetname = 'Chemistry Output Table', skiprows = [0,1,2,4,5,6,7], 
               index_col = [0,1], na_values = ['', 'na', '-'])
df.index.names = ['Field_ID', 'Date_Time']

header = pd.read_excel(path + WQ_file, sheetname = 'header data',  
               index_col = [0], na_values = ['', 'na', ' - '])
header_dict = {ah: header['name_short'].loc[ah] for ah in header.index}

analytes_excel = pd.read_excel(path + WQ_file, sheetname = 'analytes', columns = 'name')
analytes_list = [item for sublist in analytes_excel.values.tolist() …

我想第一次使用python CSV阅读器.我有一个方法要求用户选择他们想要解析的文件,然后它将该文件路径传递给parse方法:

def parse(filename):
        parsedFile = []
        with open(filename, 'rb') as csvfile:
                dialect = csv.Sniffer().sniff(csvfile.read(), delimiters=';,|')
                csvfile.seek(0)
                reader = csv.reader(csvfile, dialect)

                for line in reader:
                    parsedFile.append(line)
                return(parsedFile)

def selectFile():
        print('start selectFile method')
        localPath = os.getcwd() + '\Files'
        print(localPath)
        for fileA in os.listdir(localPath):
                print (fileA)

        test = False
        while test == False:
                fileB = input('which file would you like to DeID? \n')
                conjoinedPath = os.path.join(localPath, fileB)
                test = os.path.isfile(conjoinedPath)


        userInput = input('Please enter the number corresponding to which client ' + …

我没有重新分配open关键字，但仍然收到此错误。有任何建议或指导来纠正我的错误吗？

 with tempfile.mkdtemp() as test_dir:
        print(test_dir)

AttributeError: __enter__

我也是python的新手，我很难理解这些概念。
