Ⅰ python中我用pyinstaller打包的exe文件打不开，报错如下 是什么问题啊 F
被打包的文件:helloworld.py, 人人皆知.
打包的命令:pyinstaller -D helloworld.py
打包的console提示: 见随后的引述块
打包发布exe时的纪律(注意事项):
很简单的py脚本. Simple is better than complex. 应该遵守Python的规则.
所以在打包为exe时, 应该尽量减少没有必要的python包的导入. 否则吃的太胖
可以运行的exe文件位于:dist目录下, 而不是build目录下的.
运行后的结果:

Ⅱ python中**是啥什么意思
1、两个值相加，然后返回值给符号左侧的变量
举例如下:
>>> a=1
>>> b=3
>>> a+=b（或者a+=3）
>>> a
4
2、用于字符串连接（变量值带引号，数据类型为字符串）
>>> a='1'
>>> b='2'
>>> a+=b
>>> a
'12'
8、运算符优先级
以下所列优先级顺序按照从低到高优先级的顺序；同行为相同优先级。
Lambda #运算优先级最低
逻辑运算符: or
逻辑运算符: and
逻辑运算符:not
成员测试: in, not in
同一性测试: is, is not
比较: <,<=,>,>=,!=,==
按位或: |
按位异或: ^
按位与: &
移位: << ,>>
加法与减法: + ,-
乘法、除法与取余: *, / ,%
正负号: +x,-x
具有相同优先级的运算符将从左至右的方式依次进行，用小括号()可以改变运算顺序。

Ⅲ 美国ba专业排名大学有哪些
1、MIT——BA
MIT的BA项目2016年秋季开设，2018届的class size 30人，录取者的平均GPA达到了3.9+，GRE
quant部分168+，平均工作经验0-2年。超过80%以上的学生具有科学、数学、工程、计算机的专业背景。如果是文商社科专业的申请同学，建议一定补充CS语言和编程类的课程，其次，GT成绩争取刷到110+和750+或330+，才会有竞争力。M根据官网上提供的信息，录取者的本科大多出自名校，如Berkeley、brown、combridge、ke、Harvard、Stanford等，如果本科学校非985、211的同学，我们不建议申请。
2、UT Austin——BA
UT的BA项目隶属于McCombs商学院，为期仅10个月，夏季入学，次年夏季毕业。UT综排在美国虽然不算特别高，但是McCombs商学院在德州可以说是女神般的存在，毕业生水平在整个美国也是有口皆碑的。项目的课程设置会有三分之一的business课程，包括finance、marketing、supply
chain等方面的知识;三分之一的CS方面的课程，目前主要是Java和数据库;另外三分之一是stats的课程。这样的设置基本涵盖了做BA所需要的skillsets，到毕业的时候Java、Python、Hadoop、SAS、R、Matlab、sql等这些基本的技能应该都能掌握了。
这个学校的项目喜欢录取有理工科背景的申请者，项目size50-60人左右，中国学生10人左右，毕竟UT是个以白哥白姐为主的学校，因此不会像UCLA、USC等出现大规模的中国人。2017届的录取平均GPA3.61，GMAT719，数学和统计的相关课程分数高的申请者录取几率较大。项目就业率100%，一是项目本身有capstone，可以和大企业合作(walmart、visa、home
depot、Dell、IBM、intel等)以及当地的传统和咨询公司(四大);二是UT的商学院校友资源丰富，找工作的时候往届校友非常乐意帮助新毕业的学弟学妹们。
3、USC--BA
USC的BA隶属于Marshall school of
business，于2014年开设，在加州的BA中可以说是元老级别，因此无论是课程设置还是校友资源、业界联系可以说是目前比较成熟的体系。USC的BA项目是一个为期18个月的课程，但是大部分中国学生选择延长到两年，以更好地适应项目。33credit的毕业学分要求里面，19.5是必修，13.5是选修，如果本科修过某个特定课程的情况下，必修课程也可以waive掉换成相应的选修课程。项目的课程分为三类：general
BA，常规的BA课程设置;statistical learning
method，适合想往finance和consulting方向发展的同学;statistics modeling，适合想往更tech方向发展的同学。
USC位于LA
downtown，占据地利但也绝不限于LA地区，往届毕业的学长学姐也有很多relocate去别的地区。USC的中国同学是不少的，课程上、毕业后都可有大量的校友资源可以使用。这个学校喜欢录取GT分数高的，2016年的录取学生平均GPA达到3.63，GMAT722+,GRE320+。如果申请人又在四大或是其他big
name的公司实习或者工作过，也是个大优势。USC并不卡申请者的本科学校，有很多国内211、985，一些普通美本的同学就读，因此感兴趣的同学们GPA、GT分数够高的话，都是很有希望的。
4、Fordham--BA
福特汉姆大学位于纽约曼哈顿中心，地利位置极好，纽约市有很多世界知名公司和企业，对于毕业后想在当地找实习和工作的同学来说是个巨大的优势。2017级项目有70个人，中国学生比重高达80%，多数人本科是学会计和金融的。TG成绩需要100+和320+，项目对申请者的技术背景要求不高，成绩达到了基本录取线希望是很大的，申请时上过statistics、forecasting、modeling等课程可以加分。需要注意的是这个项目的成绩提交需要WES认证，同学们需要花一些时间做认证的准备。其次，Fordham的BA项目会有面试，网上也有很多Fordham
BA面筋总结，这里我们就不展开讲了。Fordham大学的教授和学生都很务实，比如大家会相互分享交流面试经验等，教授也会耐心地解答学生的求职问题，指导找工作等。
5、UMN--BA
UMN的BA硕士开设在其Carlson管理学院下，学制一年，共45学分，一学期要上5门课，curriculum相当intensive。暑假课程集中补习一些programming和data
analysis的知识，包括Python，R的基础，以确保学生在之后的分析课程中熟练使用。BA项目属于department of information and
decision science，UMN本身就是MIS和stat强校，再加上carlson管理学院名声在外也不错，因此UMN的BA
program的professors有很多大牛，career方面先天优势十分明显。根据去年的统计数据，项目有25人，其中大陆本3人，预计2018年会扩招。虽然UMN综排位于top50之外，可每年依然吸引着众多的申请者，建议GPA3.5+
T100+ G320+的同学可以申请。
6、GWU--BA
GWU综排56，商排30+，它的BA是由商学院department of decision
science主导的一个项目，full-time的项目时长10个月，part-time时长可达两年，项目总共40人左右，中国人大概4-5人。项目的curriculum比较偏应用，但是相关软件比如R，python，C++等等，同学们还是需要自行掌握。由于优越的地理位置，DC地区有很多私企和世界性组织的实习机会，暑假找到实习的同学还是比较多的，大部分毕业生最后都能在实习的公司留下来。
Ⅳ python2.7中如果脚本文件放在中文目录下,pymysql连接数据库会报错,怎么解决(不要修改中文目录名为英文)
解决方法为：
创建数据表时指定charset=utf8，如：
usehongxiudb;
createtableifnotexistshongxiu(
nametext,
authortext,
introtext
)engine=InnoDBdefaultcharset=utf8;
Ⅳ Python AttributeError: '_XMLTestResult' object has no attribute 'skipped'
这个代码好熟悉。差点儿就以为是我10年前写的一个自动测试框架了。
应该是你运行的结果有问题。也就是结果这个类XMLTestResult。它少了一个skipped的属性。
原因应该可能是是代码版本问题。或者是itersuite里的XMLTestResult的实例的__init__函数里的少了设计skipped这个数组。
你只要打开XMLTestResult这个类检查一下就可以。如果它是用C＋＋实现的。那么你自己在构造测试用python类时，自己加一个skipped空数组就可以。
Ⅵ Python里面的BlockWindow是个什么东西啊我学wxpython的时候提示no mole named blockwindow
BlockWindow 出现在wx教程wxpython in action书中，关于Sizer部分大量使用到BlockWindow模块。
这不是一个标准模块，而是书中之前介绍的一个自定义类，见书中327页。
源代码如下：
import wx
class BlockWindow(wx.Panel):
def __init__(self, parent, ID=-1, label=””, pos=wx.DefaultPosition, size=(100, 25)):
wx.Panel.__init__(self, parent, ID, pos, size, wx.RAISED_BORDER, label)
self.label = label
self.SetBackgroundColour(“white”)
self.SetMinSize(size)
self.Bind(wx.EVT_PAINT, self.OnPaint)
def OnPaint(self, evt):
sz = self.GetClientSize()
dc = wx.PaintDC(self)
w,h = dc.GetTextExtent(self.label)
dc.SetFont(self.GetFont())
dc.DrawText(self.label, (sz.width-w)/2, (sz.height-h)/2)
Ⅶ python pyinstaller问题
打包python脚本为exe的坎坷经历, by pyinstaller方法
又应验了那句歌词. 不经历风雨, 怎么见得了彩虹.
安装过程略去不提, 仅提示: pip install pyinstaller
打包指令
粗看包里的文档, 然后开始打包:
打开console
就用了这个命令: pyinstaller monitor_rt_quotes.py
结果就是比预期麻烦的多的多的: 干活, 硬盘不停地balabala叫, 漫长
这里记录一下控制台显示的提示信息:Writesmyscript.specin the same folder as the script.
Creates a folderbuildin the same folder as the script if it does not exist.
Writes some log files and working files in thebuildfolder.
Creates a folderdistin the same folder as the script if it does not exist.
Writes themyscriptexecutable folder in thedistfolder.
被打包的文件:helloworld.py, 人人皆知.
打包的命令:pyinstaller -D helloworld.py
打包的console提示: 见随后的引述块
打包发布exe时的纪律(注意事项):
很简单的py脚本. Simple is better than complex. 应该遵守Python的规则.
所以在打包为exe时, 应该尽量减少没有必要的python包的导入. 否则吃的太胖
可以运行的exe文件位于:dist目录下, 而不是build目录下的.

官方文档对上述指令的解释为:
|PyInstaller| analyzesmyscript.pyand:
In thedistfolder you find the bundled app you distribute to your users.
巨长的提示后, 得到了exe文件, 有18Mb的大小(太庞大了, 肥肥肥!!!), 但是结果很悲剧:
D:DBfzuildmonitor_rt_quotes>monitor_rt_quotes.exe sz000911
Error loading Python DLL: D:DBfzuildmonitor_rt_quotespython27.dll (error code 126)
估计是没有添加必要的打包选项造成的. 继续努力.
不死心! 解决问题需要由简到繁, 先从hellowworld.py做起. 搞定了.

以上代码拷贝下来保存为一个py文件，然后运行就好。
注意没有任何错误检查的。
