If you have solved some sort of coding challenges online that have to do with lists, you know that you usually need to have access to indices and also elements in it.
You may also have to do that while you are working on your tasks.

When you are about to use dictionaries, you may have cases when you try to access elements using keys that are not part of the dictionary.
Let us see the following example:
Since the key “age” is not in there, an error will be thrown.

Python is known to be the language that gives you the ability to write a few lines of code that can do a lot of things.
Just a few Python lines can be enough to pull data from an API that you can then also visualize in a fancy diagram.
Or even a single line of code can be enough for you to do plenty of things.
There are a lot of Python one-liners online that you can find.

When you create a new array in Java, you can set up the length of it. If you are programming mostly in Python these days, then you may not be aware that you can also do that in Python.
Let’s say that we have a fixed number of students and we want to save their heights in a list.
We can of course just declare an empty list and save their heights by appending new elements to the empty list.

Strings are pretty common in our day-to-day programming lives. One common task that we may need to do is perform a switch from one case to another one.
Of course, it’s not supposed to be a standalone task in Jira. Rather, it can be just a tiny portion of a larger task.
Since your time is valuable and you can invest it in more useful things, it is worth knowing that you can do such switches quickly in Python with built-in functions without having you do any implementation.
Continue readingIt can be quite common that you have to work with a list:
- You may get a list of products from an API call
- You may get a list of people from a database
- You may get a list of items in an online store by reading from a CSV file
- You may get a list of numbers from a range
The list goes on.

One task that you may have to do from time to time is to convert a string into a list of values.
This may be done in different forms, but in this article, we are going to see 2 ways.

One of the first algorithms that we are usually taught is finding either the smallest or the largest element in a list of elements by iterating through every element in a list.
Let’s assume that we are trying to find the smallest element in a list.
The algorithm is quite straightforward and intuitive even for a 5-year-old: You assume that the first element is the smallest and save its value in a variable.

It’s inevitable that you need to work with lists in your day-to-day job.
A list of users. A list of store items. A list of objects.
One potentially rare task that you may need to do is get a random element in a list.

When you see famous developers in the industry, you tend to think highly of them.
Somehow you think that you are the only person who is facing job rejections.
They are always able to get whichever job they want, and it was always like that. When we take a closer look, it cannot be further from the truth.
