Answer: For Python developers, it turns out that there are several certifications available. So, let’s take a look at what’s out there to help decide if Python certification could be good for your career.

The Most Popular (and Only) Python Certifications

The Python Institute is a training organization focused on sharpening the Python developer’s skill set. As such, they offer several certifications to demonstrate proficiency at different levels.

PCEP – Certified Entry-Level Python Programmer

As the name implies, the PCEP is the starting point to Python certification for newbies, previous programming experience optional. By the time you’re ready to test for the PCEP, you should have gained your footing in procedural programming concepts, as well as learned some Python specifics such as the language syntax and runtime environment.

Python Programming language is becoming the most demanding and useful computer programming language due to its simplicity and understanding features.
If we compare Python with other languages, python is more easily understandable and readable language. Python language has many vast applications in almost every technology sector like Data Science, Web Development, Gaming, Image processing, Data Analysing, Artificial Intelligence, etc.
Answer: What is python?

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. It’s high-level constructed in statistics structures, mixed with dynamic typing and dynamic binding, make it very alluring for Rapid Application Development, as properly as for use as a scripting or glue language to join current elements together. Pythons simple, handy to research syntax emphasizes readability and consequently reduces the price of software maintenance. Python helps modules and packages, which encourages software modularity and code reuse. The Python interpreter and the great well-known library are on hand in supply or binary shape besides the cost for all principal platforms and can be freely distributed.

Why to learn python?
  • Python is versatile. What is Python used for?
  • Python is the quickest developing programming language.
  • Python tops the listing of the most in-demand programming languages.
  • Python is convenient to read, write, and learn.
  • Python builders make magnificent money.
  • Python has a fantastically supportive community.
  • Career opportunities in python

Some of the famous job profiles after learning python are:

1.Data Analyst:-This is a very fascinating opportunity. It is specifically for these who like working with massive quantities of information and discovering which means in that data. This is once more a very famous job role. There are many groups that are searching for humans who can work with the massive units of statistics that they have to get admission to. These agencies are searching for human beings expert in Python due to the fact Pandas, SciPy, and different Python libraries come in very on hand in carrying out this task. No surprise greater and greater businesses are searching for facts analysts with a trip in python to fill open positions.

2.Product Manager:-Product managers have a very necessary position to play when it comes to supporting agencies to apprehend the market and why constructing one product will be higher than constructing another. They learn about the market, lookup for new points associated to a precise product or category, and recommend the construction of positive merchandise with facts. Data is a very vital phase of the work they do. This is why most groups nowadays are searching for product managers that are expert in python.
Answer: As an Information Technology Manager in a large corporation, I have asked the question, "Is it worth it to do a Python certification?" Many of my colleagues have told me that it is a good idea, but they were unsure if it was worth the investment. The reason they gave was that it can take six months to complete the training and another six months to get a real job. It also costs about $300 to register for the exams and training for each member of your team or department.

The simple answer is yes: However, some IT managers feel that the time investment is much less than it would cost to not go through the Python certification. They don't understand that being certified does help establish your value within the company. You are considered an expert, and this means that your opinions mean something within the company.

In addition to helping establish your expertise, you gain the added benefit of a name tag. When someone comes to the office to do a job and cannot remember your name, they will call you by your Python certification name. This can make the difference between getting the job and not getting the job. If you don't have the certification, someone else might. It can be a very competitive business world out there and every bit of advantage you gain in the marketplace, it can pay off in dollars saved and dollars earned.

Another advantage is that if you have a big company, like Microsoft, you can look forward to hundreds or thousands of free training hours. The time that you can save on doing the courses in your own time is priceless. The more knowledge you have in your own home's comfort, the more time you will have to spend on the business. You can always spread your experience as far and wide as you want to.

The beauty of obtaining your Python certification

The beauty of obtaining your Python certification online is that once you have completed the course, you have the knowledge and skills required to launch any of your ideas. The certification fee is entirely paid for in time saved, so there is no future investment.

Now, is it worth it to do a python certification? The simple answer is yes, if you are an experienced python who has created successful products or services in the past. The complicated answer is no, if you are a beginner in the business world. The certification will only come with time and experience, and you will come to realize that the knowledge you will earn will more than pay for the certification itself in the future.

      Repeat Customer email :
      Hi

      I have gone through Apache scala and spark training videos. The concepts explained very well in depth. I would like to know following details 
      1. I am interested for on Training module of Pig and Hive. While checking  found that "Hadoop Professional Training" covers pig and hive modules but not found separately.  Can I get pig and Hive module access only ? or I need to go for complete "Hadoop Professional Training" ?
      2. In addition to that, I need inputs from you. I need to go for Cloudera certificate but while checking found CCD410 "Hadoop Developer" is obsolete so if I go for "MapR Hadoop Developer Certification", what is market value? is it good to go for this exam? then interested for "MapR Hadoop Developer Certification"  Simulator  also
      I would like to know the cost for above 1 + 2.

      Thanks
