Where is PIP installed by default with Python 3.7 for Mac?

Question

I am new to Python and looking to use to to create some cool solutions. The documentation says that pip is included by default with Python 3.4+ and I've just installed version 3.7.3 but cannot located pip as I was attempting to use it to install the Requests package for API calls.

$ python3 --version
Python 3.7.3
$ pip --version
-bash: pip: command not found

So I can see in fact that version 3.7.3 of Python is installed, yet pip isn't? I checked both Library/Python/3.7/bin/ and Library/Python/3.7/lib/python/site-packages/ and do not see any reference to pip.

The documentation states that you can use a curl command to get pip and then install it. I am new to the terminal and have never used a curl command. Also, I've read you want to keep your Python3 stuff away from the system Python version, so would I use the following?

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ python3 get-pip.py

Answer 1

您需要使用python3 -m pip .....来表明您正在使用Python 3，否则它将使用默认的Python 2

Answer 2

The following worked for me:

$ which pip3.7

which returned

/Library/Frameworks/Python.framework/Versions/3.7/bin/pip3.7

The purpose of my question was to find out if pip was installed so i could use it to get another package. It was, so I ended up doing the following with success.

$ pip3.7 install requests

which returned

Installing collected packages: idna, urllib3, chardet, certifi, requests
Successfully installed certifi-2019.3.9 chardet-3.0.4 idna-2.8 requests-2.22.0 urllib3-1.25.3

I'd imagine that since I only installed Python3.7 on my mac and since pip3.7 was included, i could have likely input pip3 install requests although I am not sure if there were other versions of pip installed prior what would happen, maybe someone could clarify in comments about the nuances.
