Issue on Installing Anaconda for Windows 10

I installed Anaconda 3 (Python 3.7.3 64-bit) from file Anaconda3-2019.03-Windows-x86_64.exe but I can't find Anaconda Navigator between my desktop apps. I followed some (very) similar questions on this forum but, e.g. after having opened the command terminal and dialed the command:
anaconda-navigator
I obtained the error text:
'anaconda-navigator' is not recognized as an internal or external command, operable program or batch file.
How do I fix this? Thank you!
I had the same problem on windows 10 64x, the only way to make it work was by uninstalling python and anaconda and installing the anaconda 86x.

getting the wrong version of python

I have installed python 3.6 on my laptop but when I run the version command I get the 2.7 version. I have changed the path variable and still get the same result and the funny thing is that I don't even have python 2.7 installed on my laptop.
here is the image path variable and version also when I run python in cmd I get the error run error any help will be much appreciated
Typing:
where -a python
shows you the order in which the command
python
is found on your path.
Use:
which -a python
on unix-like systems such as Linux or MacOS X.

How to use pip with Visual Studio Code

I have python 3.6 installed, I have a python extension installed on Visual Studio code but I still can't use pip on Visual Studio code. It says it is not a recognised command. Any help please?
Update: I tried installing pip manually but a file in python2.7 keeps stopping. What's bothersome is that I uninstalled python 2.7 ages ago and I've currently removed every folder with it but python-V still says I have python2.7.6 installed.
I'm on windows 10
I found some solution on this website:
https://pip.pypa.io/en/stable/installing/
If you use Visual Studio Code, you can type the following command:
C:\> py -m pip
If everything is alright, you should see the list of commands, which you can use. They are listed in your terminal, as per below.
I also would advise you to check/select the version of Python you are using:
VSCode: There is no Pip installer available in the selected environment
I am pretty sure your problems of VSCode not finding the correct version of Python will be resolved if you add your ( Python 3.6 installation ) location to the system path.

Twice version of python in Ubuntu

I wold like to use Pycham with Python3.4.3 and Pyqt4.
So, I have installed Python 3.4.3 in Ubuntu 16.04 and run PyQt4 as well. After that, I continued installing Pycharm. However, pycharm interpreter didn't recognized these version of python. It only shows python 3.5 and 2.7 version. However, when I run in terminal python3.4>>import PyQt4, there isn't wrong message. I think that all compilation that I have to do was right. Anyone know what can I do to fix this problem?
How can I put Pycharm to recognize python3.4.3 that I installed with PyQt4?
