Learning Path: Python: Guide to Become a Python Professional

This video provides an overview of the entire course.

Choosing the correct name is essential to make our programs more readable and ease the process of designing software and applications. Complex names could lead to confusion. This video will guide you to select the appropriate names while designing an application.

Many programming languages make a distinction between integers, bytes, and long integers. Some languages include distinctions for signed versus unsigned integers. How do we map these concepts to Python? This video will walk you through these concepts in detail.

Python offers us several ways to work with rational numbers and approximations of irrational numbers. We have three basic choices, which are Float, Decimal, and Fraction. With so many choices, when do we use each of these? This video will let you answer this question.

This video will let you understand which division operator to use while converting numbers from one base to another

How can we rewrite an immutable string? This video will answer this question and show you how to work with strings in Python.

The easiest way to decompose a complex string is by generalizing the string into a pattern and then writing a regular expression that describes that pattern.This video will let you know how to do it in a smart way!

Creating complex strings is, in many ways, the polar opposite of parsing a complex string. Let’s dive into building a complex string.

There’s another way of building complex strings, which is, from a list of characters. This video will walk you through the steps that let you build a complex string from a list of characters.

Our Computers work a lot with Unicode, and sometimes, we are not aware how to use them. This video will let you know how to use Unicode and the internal operations on them.

How do we map Unicode characters to bytes for writing to a file or transmitting? This video will show you, how to achieve this goal.

How can we work with files that aren't properly encoded? What do we do with files written in the ASCII encoding? How do we decode the characters from that stream of bytes? This video will answer all these queries.

How can we keep things, which are pairs, such as latitude and longitude, together? Let’s see how to do this!

You need to write Python script files in order to do anything truly useful. How can we avoid syntax errors and be sure that our code matches what's in common use? This video will provide a resolution for these tasks.

There are many times when we need to write lines of code that are so long that they're very hard to read. How can we break long Python statements into more manageable pieces? Let’s explore this.

When we have a useful script, we often need to leave notes for ourselves and others, on what it does, how it solves some particular problem, and when it should be used. This video contains a suggested outline so that the documentation will be reasonably complete.

When we have a useful script, we often need to leave notes on what it does, how it works, and when it should be used. Many tools for producing documentation, including Docutils, work with RST markup. What RST features can we use to make our documentation more readable? Let’s dive into it!

When designing a complex chain of if and else statements, we might miss some condition that got lost in the tangle of logic. Missing this will mean that our program will fail to work properly. How can we be sure we haven't missed something? This video is an answer to this question.

There are a few situations, where we don't have the data until we get an input from the person. Let’s have a look at how we could implement a while statement in these conditions.

What could you do when you have multiple break statements, each with its own condition. How can you minimize the problems created by having complex break conditions? Let’s get the answer for these questions.

How could we avoid confusion due to hierarchy if we're trying to handle detailed exceptions as well as generic exceptions? This video will give a few of the best exception matching rules.

There are some common mistakes in exception handling. These can cause programs to become unresponsive. This video will show some common exception handling errors that we can avoid.

In some cases, we may want to merge some seemingly unrelated exceptions into a single generic exception. What if we need to provide supporting details that amplify or extend the generic exception. We can do this by chaining from the generic exception to the root cause exception. Let’s see how to do this.

There are many instances where our scripts will be entangled with external resources. We'd like to isolate each entanglement so that we can be sure that the resource is acquired and released properly. Let’s see how we could achieve this goal.

When we define a function, we often have a need for optional parameters. This allows us to write functions that are more flexible, and can be used in more situations. Let’s see how to design these functions.

In some cases, we want to provide a simple, high-performance software implementation that can perform different calculations based on what's known and what's unknown. We don't want to use a general algebraic framework; we want to bundle the different solutions into a simple, efficient function. This video will demonstrate how you could do this.

What if you have a large number of positional parameters to a function? What would you do when it gets difficult to remember the required order for the parameters and there are too many parameters? Let’s answer these questions.

Sometimes we want hints about the type of data involved, which can be used for testing and confirmation but don't interfere with performance. How can we provide meaningful type hints? Let’s see how we could achieve this goal.

What could be done if we’d like to provide a way to make the common parameters slightly easier to work with than the uncommon parameters and to avoid having to repeat the parameters that are part of a larger context? Let’s have a resolution to this situation.

How can we clearly document what a function does? Can we provide examples? Let’s explore the answers to these questions.

Let’s see how we could use a simple and smart way to design recursive functions to enhance the structure of our program.

How can we import the functions or classes from a file without having the script start doing something? Let’s see how to do this.

How do we choose which structure to use? What are the features of lists, sets, and dictionaries? Why do we have tuples and frozen sets? Let’s answer these questions with this video.

Can we control the formatting in our programs? Can we change the extra characters that are supplied? Let’s see how to do this.

There are many times when we want to pick items from a list. One of the most common kinds of processing is to treat the first item of a list as a special case. This leads to a kind of head-tail processing where we treat the head of a list differently from the items in the tail of a list. Let’s see how we can slice or dice a list.

There are many times when we want to remove items from a list collection. We might delete items from a list, and then process the items that are left over. Let’s see how to do this.

We generally want to display the values with the most significant digit first. This leads to a need of reversing the sequence of digits in a list. This video will let you do this in Python.

Can we control the formatting in our programs? Can we change the extra characters that are supplied? Let’s see how to do this.

Python gives us several ways to remove items from a set collection. Let’s dive into few of these.

Through this video, you will be able to use a dictionary when you have some key that we need to map to a given value along with some key operations like inserting and updating dictionaries.

This video will show you how to define a service that works in a simulated environment with a single processing thread and avoid concurrency and multi-processing considerations.

What if we want to keep the keys in a given order so that the dictionary follows the structure of the source file? Let’s see how we could do this.

How can we be sure our doctest examples really work? Let’s get the answer to this.

How do variables really work? What happens when we assign a mutable object to two variables? Let’s have the answer to these questions.

This video will walk you through different ways to break the connection that exists when two variables are references to the same underlying object

This video will let you have a close look at the consequences of a mutable default value for a function parameter and how to avoid it.

Can we control the formatting in our programs? Can we change the extra characters that are supplied? Let’s see how to do this.

The environment variables are available through the os module. How can we have an application's configuration based on these OS-level settings? Let’s have a close look at this.

There are some kinds of formatting options available in Python. What if we want more flexible output? Let’s see some amazing options for this, which are there for you in Python.

In some cases, we may want to get the user input from the OS command line without a lot of interaction. We'd prefer to parse the command-line argument values and either perform the processing or report an error. How do we parse argument values from the command line? Let’s start doing this with this video.

There are several ways of creating interactive applications. Let’s see how we can prompt the user for input and then invoke a specific method of the class we provide.

The environment variables are available through the os module. How can we have an application's configuration based on these OS-level settings? Let’s have a close look at this.
