如果pip也要安装，请安装python包？

我下载了python3并安装了它，我发现pip3也安装了

aircraftdeMacBook-Pro:~ ldl$ which python3
aircraftdeMacBook-Pro:~ ldl$ which pip3
....there I install the .dmg for python3 I download from the upper link.
aircraftdeMacBook-Pro:~ ldl$ which python3
/usr/local/bin/python3
aircraftdeMacBook-Pro:~ ldl$ python3 --version
Python 3.5.2
aircraftdeMacBook-Pro:~ ldl$ which pip3
/usr/local/bin/pip3 

因此，我想确认pip3包是否包含在

.dmg

文件中，因为安装python3时也会安装pip3

aircraftdeMacBook-Pro:~ ldl$ which python3
aircraftdeMacBook-Pro:~ ldl$ which pip3
....there I install the .dmg for python3 I download from the upper link.
aircraftdeMacBook-Pro:~ ldl$ which python3
/usr/local/bin/python3
aircraftdeMacBook-Pro:~ ldl$ python3 --version
Python 3.5.2
aircraftdeMacBook-Pro:~ ldl$ which pip3
/usr/local/bin/pip3 

从命令行中可以看到我只安装了python3

dmg

，但也安装了pip3。

这是意料之中的

aircraftdeMacBook-Pro:~ ldl$ which python3
aircraftdeMacBook-Pro:~ ldl$ which pip3
....there I install the .dmg for python3 I download from the upper link.
aircraftdeMacBook-Pro:~ ldl$ which python3
/usr/local/bin/python3
aircraftdeMacBook-Pro:~ ldl$ python3 --version
Python 3.5.2
aircraftdeMacBook-Pro:~ ldl$ which pip3
/usr/local/bin/pip3 

较新版本的Python 3（3.4+？）预装了pip以及模块
