苹果手机怎么下载python3.7.4

从底部链接中下载好安装包，对着他右击。
解压到Python 3.7.4 32 64位，解压完成后双击打开Python 3.7.4 32 64位文件夹.
2.然后，根据自己系统选择是安装32位还是64位.
3.然后，勾选Add Python 3.7 to PATH，然后点击Customize installation
4.然后，点击Next
5.然后，点击红框旁边的Browse（浏览）按钮选择你想要的安装的位置，或者直接在红框中改成你想安装的位置，然后点击Install
6.然后，正在安装，点击Close，点击左下角微软图标按钮，找到Python 3.7，点开，对着IDLE (Python 3.7 64-bit)右击，发送到桌面快捷方式，桌面找到IDLE (Python 3.7 64-bit)图标双击打开.

如何在 Mac OS X 上安装 Python3.3

***隐藏网址***

方法一：

在命令行

***隐藏网址***
brew install python3

就可以用了，简单明了。

方法二：

去python.org下载python3.3的源代码包，调整好Setup.dist，然后./configure && make && sudo make install自己编译下python3就可以了。

最后把/usr/bin/python移动到一边,ln链接下新的python就可以使用了。

其他人也有写用pyenv安装与管理不同版本python可以直接：pyenv install 3.5.0

苹果电脑怎么安装python123考试端

1、通过brew安装python3环境。
2、前往官网下载软件。
3、有安装包的话也可通过U盘安装。

如何在苹果系统上安装PyQt4

安装PtQt4前你需准备： 

1. Xcode （10.6.1 自带Xcode）

2. Qt 

3. SIP 

4. PyQt4 

创建了一个pyqt文件夹在硬盘根目录下，并将sip-4.12.1.tar.gz和PyQt-mac-gpl-snapshot-4.8.4.tar.gz放到其中并解压。

1、先安装qt，默认安装，这一步大部分人不会有问题，跳过。

2、接下来，打开终端(Terminal，在 Applications(应用程序)/Utilities(实用工具)/ 下)，在终端输入：export VERSIONER_PYTHON_PREFER_32_BIT=yes。

3、使用"cd 路径"命令将当前目录设为sip-4.12.1，如：  cd /pyqt/sip-4.12.1/， 然后进行配置(configure)【Re-build SIP in 32bit 】在终端中执行

python configure.py --arch i386
配置(configure)完成后就开始编译，在终端中执行引用make clean(清除以前的安装信息)make
编译完成后就安装，在终端中执行引用sudo make install

在这个过程中没出现错误就是安装成功了 
编译安装PyQt4，过程和上面的一样。 【Build PyQt4 in 32bit 】
在终端中使用"cd 路径"命令将当前目录设为PyQt-mac-gpl-snapshot-4.8.4，如

引用cd /Users/schi/pyqt/PyQt-mac-gpl-snapshot-4.8.4
然后进行配置(configure)，在终端中执行引用python configure.py --use-arch i386
配置时会遇到引用Determining the layout of your Qt installation... 
This is the GPL version of PyQt 4.6 (licensed under the GNU General Public 
License) for Python 2.6.2 on darwin. 
Type ’2’ to view the GPL v2 license. 
Type ’3’ to view the GPL v3 license. 
Type ’yes’ to accept the terms of the license. 
Type ’no’ to decline the terms of the license. 
Do you accept the terms of the license? 

输入yes，再按回车就行 
配置(configure)完成后就开始编译，在终端中执行

引用make cleanmake

编译比较花时间，请耐心等待。

编译完成后就安装，在终端中执行

引用sudo make install

在这个过程中没出现错误就是安装成功了  
也可以在IDLE中导入PyQt4的模块，能成功导入就说明安装成功

Python代码 

from PyQt4 import QtCore, QtGui  

下面分析一下安装过程中可能遇到的问题：

1.问题如下

##############

ld: warning: in /Library/Frameworks/Python.framework/Python, missing required architecture x86_64 in file
Undefined symbols:
  "_Py_Initialize", referenced from:
      PyCustomWidgets::PyCustomWidgets(QObject*)in pluginloader.o

      PyCustomWidgets::getModuleAttr(char const*, char const*)in pluginloader.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make Error 1
make: *** Error 2
这个问题的原因就是：qt是在32位mac上编译的，但pyqt默认是在64位机子上编译的，所以我们在编译的时候要制定编译环境：是i386 还是x86_64.

请参考如下的信息：

The problem is that the Qt library is 32bit while, by default, python builds PyQt4 in 64bit. That caused problem when it tried to link 64bit object files with 32bit Qt library. To fix this issue, we need to force python to build PyQt4 in 32bit, and we also need to re-build SIP in 32bit mode. If you use the python version that comes with Mac OS (2.5 for Snow Leopard), make sure that it runs in 32bit mode by issuing the command

2.个问题如下：

》》》 from PyQt4 import QtGui

Traceback (most recent call last):

File "《stdin》", line 1, in 《module》

ImportError: dlopen(/Library/Python/2.6/site-packages/PyQt4/QtGui.so, 2): Symbol not found: __ZN13QPyTextObject16staticMetaObjectE

 Referenced from: /Library/Python/2.6/site-packages/PyQt4/QtGui.so

Expected in: flat namespace

in /Library/Python/2.6/site-packages/PyQt4/QtGui.so

这个问题是所有的包安装都没有问题但是当导入QtGui或其他包时，总报这个问题，这个问题的原因是，当前pyqt release的包本身带的一个bug，PyQt-mac-gpl-snapshot-4.8.3， 所以你下载下个要release的包就可以了。如我下的是：PyQt-mac-gpl-snapshot-4.8.4。

苹果电脑怎么下载python

• 为了启动IDLE需要在Mac上找到终端，一般在控制台找到“其他-终端”。也可以直接搜索在输入框中搜索“终端”

  请点击输入图片描述

• 2

  终端启动后输入命令“idle”并“Enyer”键盘，这是会弹出新页面。

  请点击输入图片描述

• 3

  弹出新页面如下图。这是python shell。python已经运行并等待你输入命令。现在我们可以看到python已经安装成功。

  请点击输入图片描述

• 4

  为了检验是否安装成功，我们继续输入 print “Hello worid!” 并按“Eenter”看是否能答应如下图。
