Error in installing Python 3.7 - E: Sub-process /usr/bin/dpkg returned an error code (1) - python-3.7

Question

I was trying to install python 3.7 in my Ubuntu virtualbox using 'sudo apt-get install python3.7'.
However, I got the below output: -
Building dependency tree
Reading state information... Done
python3.7 is already the newest version (3.7.4-2~16.04.york1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libpython3.7 : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
libpython3.7-dev : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
libpython3.7-stdlib : Depends: libpython3.7-minimal (= 3.7.4-1+xenial2) but 3.7.4-2~16.04.york1 is to be installed
python3.7 : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Afterwards, I tried executing 'apt-get -f install' as recommended in the above output, but then I got the below: -

Update:
Even though the error says that python3.7 is already there, when I execute python, I get the below:
Python 2.7.12 (default, Oct 8 2019, 14:14:10)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And below when I run 'python3': -
Python 3.5.2 (default, Oct 8 2019, 13:06:37)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
All I want to do is to install python 3.7.
Can anyone kindly help me with this error?

Answer 1

I see following in your logs
python3.7 is already the newest version (3.7.4-2~16.04.york1).
It says python3.7 is already install.
can you just try
python or python3 on command line, see what it says?
if you see something like below, it has successfully installed
Python 3.7.3 (v3.7.3 Oct 3 2017, 00:32:08)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on XXX
