One of the student in Rutherford’s class was very hard working. Rutherford had noticed it and asked one evening:

If you want to repeat a character N times on a bash shell, say for example your
variable name is
aaaaa; Then a simple way to do it is not writting it
repeatedly 5, do this:
Initial Prompt: me@me $
Step 1 : Alt + N
Prompt : (arg: N)
Ex : Alt + 5 ==> (arg: 5)
Step 2 : (arg: N)
Final Status: me@me $ aaaaa

The usual algorithm related coding challenges are all over the place in the internet. But I saw some projects, in a way we could also put it as challenges which helps in learning a lot of new things. Below I am trying to compile a list of similar kind of projects:

Straight forward method to relocate virtualenv folder to a different directory from the documentation
It does not work in all situation as per what we can see in the Github issues and it is also mentioned in their documentation itself that, this feature may be removed in future releases.
But I had this problem that I was not able use pip to get the packages installed
pip freeze. It says that the python executable path was wrong as it pointed
to the old path.
I got the code below from SO
Got to run the below code after activating the virutalenv(
import pip #needed to use the pip functions for i in pip.get_installed_distributions(local_only=True): print(i)
This actually helped me in getting the list of packages without directly using pip.
