为什么我的pycharm缺少很多方法的自动提示_course

RT，在看《Python编程 入门到实践》中用Pygame开发游戏的例子，但是我导入了pygame包之后，感觉书里面的很多方法pycharm都不给自动提示啊！！憋屈的不行，难道要把这些函数都记住嘛？？

python使用pycharm中的jieba库应用未成功_course

1.首先自己在pycharm中安装了jieba库  2.然后在运行程序过程中出了name 'jieba' is not defined的问题  ==================================  想问问大哥们，该怎么搞，还是个小白，很多问题都能自己百度，但是这个问题我一直没有找到合适的答案，如果能帮我解答一下万分感谢！！！！

关于pycharm的编译环境设置_course

因为是在学校的机房,每次重启C盘都会被还原。课题要用到anaconda的编译环境，但是每次重启后pycharm的编译环境都会被还原到python3.6，重新修改为anaconda因为电脑配置关系又会花费大量时间，有没有办法让默认编译环境不受C盘还原的影响呢？ 对了，说起来每次重启pycharm的项目编辑记录也不见了（就是关机前我在编辑的那个项目，重新打开pycharm按理会自动打开，但是还原后打开的是另外的项目），应该也是被还原了，保存记录文件或许能解决这个问题？能在哪里找到pycharm的记录文件呢？ orz问题可能很蠢，希望大佬们bu'yao'jie'yi

python unittest执行程序在pycharm可以成功运行但使用cmd会报错_course

如题，在pycharm中执行主程序运行成功： 已连接主机 登录成功 正在发送...... 邮件发送完成~ Process finished with exit code 0 在cmd执行主程序报错： Traceback (most recent call last): File"all_test.py",line 32,in<module> alltestnames = creatsuite() File"all_test.py",line 27,in creatsuite testunit.addTests(test_case) File "C:\Python37\lib\unittest\suite.py",line57,in addTests for test in tests: TypeError:'_FailedTest'object is not iterable 报错的程序代码是这部分： def creatsuite(): testunit = unittest.TestSuite() test_dir = test_suite_dir package_tests = unittest.defaultTestLoader.discover(test_dir, pattern='*.py', top_level_dir=None) for test_suite in package_tests: for test_case in test_suite: testunit.addTests(test_case) print(testunit) return testunit 刚接触接口测试，请问是哪里出了问题呢？因为正在jenkins构建项目执行，把源码放在github后使用windows批处理命令执行，这样进程是停滞的，也结束不了。

来自php的python调用中的MemoryError_course

<div class="post-text" itemprop="text"> <p>I'm getting an annoying error without an apparent reason.</p> <p>Here's the setup: I have a python script (Python 3.6 anaconda distribution) which is being called from Php (7.2.6) all on CentOS 7. </p> <p>The PHP to Python call is via <strong>exec</strong>, and looks like this</p> <pre><code>exec("LANG='en_US.UTF8' " .

Python 2.7：如何构建getter / setter函数来访问没有继承的类属性？_course

<div class="post-text" itemprop="text"> <p>this is probably a super nub question, apologies. I'm trying to achieve an effect in Python I am familiar with from PHP, which is building getter and setter functions for private attributes.</p> <p>In PHP I will commonly do something like this:</p> <pre><code>&lt;?php class newClass() { private $var = null; function newClass($initVal) { //init } public function get($var) { if ( isset($this-&gt;$var) ) { return $this-&gt;$var; } } } ?&gt; </code></pre> <p>But, trying the same idea in Python:</p> <pre><code>class newClass(): def __init__(self, initVal): self.__nameOfVar1 = initVal self.__nameOfVar2 = initVal def get(self, var): #assuming, when called, var = nameOfVar1 if self.__var: return self.__var </code></pre> <p>Throws an error <code>AttributeError:'newClass' object has no attribute '__var'</code></p> <p>And quite rightly so, it doesn't. How do I build getter and setter functions to access private attributes?</p> <hr> <p><strong>UPDATE:</strong></p> <p>I've left the original question because it seems useful for new comers to Python to learn which conventions from other languages they might accidentally be bringing forward. But in reality, my initial problem was a bit different, in attempting to make the problem more general I obfuscated my actual need. So here's an amendment:</p> <p>In fact I was not working with private attributes; in fact, I am dealing with trying to pass an attribute downward through a composition circumstance. ie:</p> <p><code>Class A</code>, as an attribute, has a <code>Class B</code> object that does not inherit from <code>Class A</code> . It is almost never the case that <code>Class B</code> needs any information from <code>Class A</code>, but in my project there is one circumstance where, if a user chooses not provide information to <code>Class B</code>, there is a statement that makes a last-ditch attempt to infer a reasonable solution, but it requires information from <code>Class A</code> that, normally, it never needs. </p> <p>I could build <code>Class B</code> to always have had that information, but that means that almost always I'm just wasting that time and memory (trivial though it might be). To make this concrete, imagine this:</p> <p><code>toothbrush</code> has <code>bristles</code>, and <code>bristles</code> can, provided the user supplies a preferred brushing experience, create a number of bristles appropriate to either a "soft" or a "firm" brush. But, if the user doesn't provide this, then I'd like <code>bristles</code> to ask <code>brush</code> for it's surface area, allowing it to guess what an average number should be. </p> <p>I came up with this, though I have the intuitive sense that Python programmers will hate me for it; I'd just like to understand why:</p> <pre><code>@staticmethod def request(self, var): appIndex = self.__dict__ if appIndex[var]: return appIndex[var] print Class.request(instance, var) </code></pre> <p>Works like a charm, but I think this is Python heresy. <em>Why?</em></p> </div>

Pycharm每次都要加载tensorflow_course

如题。我安装的是Win10+CUDA9.0+cuDNN9.0+tensorflow1.7+Pycharm tensorflow已经是通过pip安装了。在CMD界面写import tensorflow是没有问题的。 在Pycharm里面新建一个工程都要重新在setting->project interpreter加载tensorflow,很慢！ 而且，我在Python安装路径下面，D:\Program Files (x86)\Python\Lib\site-packages，里面有tensorflow和tensorflow_gpu-1.7.0.dist-info两个文件夹。我需要的是GPU版的，这两个文件夹有什么区别呢？这里面都没有python.exe！ 我在网上查到的不少都是用Anaconda的，直接在Pycharm里面把设置改为tensorflow里面的python.exe就行了。 请问我如果不装Anaconda有没有一劳永逸的让Pycharm自己加载的方法呢？还是说用Pycharm只能是用Anaconda最方便？ 谢谢！
