Python offers several advantages for application development, including reduced development time and effort. 

It is ideal for prototyping due to its robustness, scalability, speed, and versatility, making it suitable for both small-scale and enterprise-level projects.

According to a research by iDataLabs – 69% of companies that use Python are small (<$50M in revenue), 9% are medium-sized ($50M – $1000M in revenue) and 16% are large (>$1000M in revenue).

Python provides a database API that simplifies connections to databases like MySQL, Oracle, and PostgreSQL. 

Its ability to interface with languages such as C and Java allows developers to leverage functionality from other programming languages in Python applications.

Python is often likened to building blocks that can be combined to create new applications. By carefully selecting and integrating these blocks or modules, developers can create applications more efficiently. 

Additionally, Python’s open-source nature enables developers to contribute new packages to solve problems and share them with the community.

     6. Python for automation scripts

Python excels in scripting, allowing developers to write small programs that perform multiple tasks automatically. 

It is ideal for such purposes as it emphasizes quick and easy coding. Web scraping, for instance, is a popular use case of Python scripting. 

It involves parsing websites and extracting relevant data, which can then be stored in formats like CSV for further analysis using machine learning algorithms.

    7. Python in Fintech

Financial technology or Fintech, is a technology that automates and improves the delivery of financial services. 

This includes online banking, stock market trading, online transactions, and bitcoin transactions using blockchain applications.

Fintech is utilized in various finance-related sectors such as investment, portfolio management, banking, education, and fundraising.

According to a survey by HackerRank – Python is among the top three most popular languages used in financial services companies and one of the top languages in FinTech.

Python’s ease of use and modular nature makes it the perfect programming language for Fintech.

It is also an ideal choice of programming language for fintech because it can be employed for machine learning and data science libraries and capabilities.

For example, using machine learning to automatically detect fraud through payment history can save companies millions of dollars. 

That’s why top financial institutions like Stripe, Revolut, and Robinhood incorporate Python in their software development.

Furthermore, Python finds application not only in Fintech but also in other industries such as game development, GUI application development, networking, testing, robotics, and embedded applications.

Advantages of Python Programming Language

  • Easy to Learn and Write:

Python is a high-level programming language with a syntax that resembles natural language. This makes Python easier to read and understand, requiring fewer lines of code compared to other languages like C/C++ and Java.

  • Improved Productivity:

The simplicity of Python allows developers to focus more on problem-solving rather than spending time understanding complex syntax. This leads to writing less code and achieving higher productivity, as well as faster debugging.

  • Interpreted Language:

Python is an interpreted language, executing the code line by line. It stops execution and reports errors if any are encountered. Debugging becomes easier as Python provides feedback on the first encountered error, even if multiple errors exist.

  • Typed Dynamically:

Python doesn’t know the type of variable until the code is run. It automatically assigns the data type during execution. Python application developers don’t need to worry about declaring variables and their data types.

  • Free and Open-Source:

Python is free to use and distribute due to its open-source license. Users can modify the source code and distribute their own versions of the Python programming language.

  • Vast Libraries:

The Python library is huge where you can find almost all the functions you need to perform coding tasks. Python application developers don’t have to depend on external libraries.

If you intend to use an external library you can use Python package manager (pip) which makes it easier to import other packages from Python package index (PyPi) which consists of over 2 million packages.

  • Portability:

In other languages such as C and C++, you need to change the code each time you run on different platforms but with Python you can write it once and run it anywhere.

Disadvantages of Python Programming Language

  • Slower Speed:

As mentioned above, Python’s nature as an interpreted language means that it executes each line of code sequentially, resulting in slower execution.

The dynamic nature of Python is also responsible for the slow speed of Python because it has to do extra work while executing the code.

  • Python is not Memory Efficient:

Python’s usage of memory for storage and execution is significantly higher than that of other programming languages, which renders it unsuitable for constructing applications that require memory optimization.

  • Inefficient Mobile Computing:

Python is typically used in server-side programming. Because Python is not memory efficient and has a slow processing power it is not the most suitable application development technology for mobile app development.

  • Database Access:

Python application development is stress-free but interacting with databases is slower because Python databases are still slower and somewhat outdated compared to other popular technologies.

6 Common Mistakes Python Developers Should Avoid

Posted on by Beatrix Potter

Because Python has such user-friendly syntax, developers sometimes miss out on the scope of the diverse Python language. Here are 6 common mistakes that developers typically make.

1. Expressions that are incorrectly used as defaults for function arguments

A great thing that Python does is that it lets you specify that a function argument is option. It does this by creating a default value for it.

However, confusion can manifest when the default value is mutable. A mistake that happens regularly is to assume that the optional argument will be set to the specified expression every time the function is called.

This is done without supplying the optional argument with a value.

2. Error handling and Incorrect Indentation

A traceback is a very specific form of error in Python. Forgetting a colon at the end of a line, forgetting a parenthesis, or by mistake, when working on an if statement, adding one extra space, will lead to a syntax error.

Even if a seemingly small error, if this happens Python cannot understand how to read the program you created.

To create a block code, you need to indicate each line of the block. Each block code must be indicated by the exact same amount to work.

Python is unique compared to other languages, in that indentation has more of a role than making code look clean. Indentation is required for illuminating what block of code a statement belongs to.

Indentation is depended on by many characteristics. Something difficult to deal with is that some indentation errors are more problematic to spot than others.

An example: differentiating spaces and tabs in code, and what the error associated with it is. Python and the editor may see different things when the tabs are counted by a number of spaces.

You must use either all spaces or all tabs within the entire code block.

3. Variable binding

Python, with its late-binding behavior, creates confusion among developers on how Python binds its variables.

It binds its variables in closures or surrounding global scope. This leads to values of variables in closures looking up at the time the inner function is called upon.

4. Incorrectly using the __init__ method

A reserved method called init, it is a constructor and is utilized when python allocates memory to a class object that is new.

If you try to explicitly return a value from the init method, this will make it seem that the person using it is trying to diverge from the actual purpose.

5. Having a clashing name with Python Standard Library modules

Library modules that come with “out of the box” are plentiful in Python and is one of best features of it.

However, the result of this can be creating a name clash between one of the module names in the Python Standard Library and the name you created for on of your modules.

An example of this is naming a module email.py in your code. There then is the same name within the standard library module, creating a clashing of names.

The name clash leads to a multitude of different problems, including problems like importing another library which in turn tries to start importing the Python Standard Library version of a module, but instead starts importing your version of the same name. Yours will be imported instead of the one within the Python Standard Library.

This is a slippery slope as it will create even more problems for you.

It goes without saying, but make sure you use extra caution when naming. Do not use the same names as items within the Python Standard Library modules.

Always take the easier route of renaming the module within your package then trying to take the inefficient steps of requesting a name change by filing a Python Enhancement Proposal.

6. LEGB Rule

Local, Enclosing, Global, Built-in, if a user makes an assignment to a variable in a scope, Python automatically considers that variable to be local to that scope.

It shadows any similarly named variables in the outer scope. The most common time this is a mistake is when using lists.

A high-level programming language with dynamic semantics, Python is very attractive for Rapid Application Development. Avoid mistakes with these tips.
