Getting unique elements from List

mylist = [1,2,3,4,5,6,6,7,7,8,8,9,9,10]

Using Simple Logic from Sets - Sets are unique list of items

mylist=list(set(mylist))

Generator(s): python

Yield result one by one!

Generators are used to create iterators, but with a different approach. Generators are simple functions which return an iterable set of items, one at a time, in a special way.

When an iteration over a set of item starts using the for statement, the generator is run. Once the generator's function code reaches a "yield" statement, the generator yields its execution back to the for loop, returning a new value from the set. The generator function can generate as many values (possibly infinite) as it wants, yielding each one in its turn.

Explain all the file processing modes supported by Python ?

Python allows you to open files in one of the three modes. They are: read-only mode, write-only mode, read-write mode, and append mode by specifying the flags r, w, rw, a respectively.

A text file can be opened in any one of the above said modes by specifying the option t along with r, w, rw, and a, so that the preceding modes become rt, wt, rwt, and at.

A binary file can be opened in any one of the above said modes by specifying the option b along with r, w, rw, and a so that the preceding modes become rb, wb, rwb, ab.

A quick guide on getting ready for tech interviews.

Chitchat like a pro.

Before diving into code, most interviewers like to chitchat about your background. They're looking for:

Metacognition about coding. Do you think about how to code well?
Ownership/leadership. Do you see your work through to completion? Do you fix things that aren't quite right, even if you don't have to?
Communication. Nerd out about stuff. Show you're proud of what you've done, you're amped about what they're doing, and you have opinions about languages and workflows.
STAR (Situation, Task, Action, Result). It’s good to have a project in your back pocket that you can talk about in a direct and concise way.
