Data Science is a multifaceted field used to gain insights from complex data. Data Science is a blend of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data.
Data Science is primarily used to make decisions and predictions making use of predictive causal analytics, prescriptive analytics (predictive plus decision science) and machine learning. Data Science can help you make informed decisions, create beautiful visualizations, and even try to predict future events through Machine Learning.
Data science is just about as broad of a term as they come. It may be easiest to describe what it is by listing its more concrete components i.e. Data exploration & analysis : Pandas; NumPy; SciPy; a helping hand from Python’s Standard Library and Data visualization - Taking data and turning it into something colorful : Matplotlib; Seaborn; Datashader.
Data science iencompasses a wide range of fields: Mathematics, Statistics, Python, Applying advanced statistical techniques in Python, Data Visualization, Machine Learning, Deep Learning, and the like.
Companies are looking for data-driven decision makers, and this Data Science course by Uplatz, taught by our elite tutor Imad Jaweed, will teach you the skills you need to become just that.

Python certifications are a kind of credential. Credentials are largely how the traditional education system works. Employers use that credential as a proxy for experience when deciding whether to hire you. It’s proof that you’ve learned the things you say you’ve learned.
As less-conventional paths to education like MOOCs have become more popular, they have replicated the credential that comes with a degree by offering online certificates. Additionally, many stand-alone companies offer certifications that aim to replicate the degree credential.
The Python Institute is committed to the development of an independent global standard in Python programming certification, which will allow programming specialists, software developers, and IT professionals from all over the world to assess and document their programming skills objectively, and to gain recognition for their expertise.
The Python Institute offers perhaps some of the most well-known Python certifications. It offers four primary certificate level exams:
• Certified Entry-Level Python Programmer (PCEP) —
• Certified Associate in Python Programming (PCAP) —
• Certified Professional in Python Programming 1 (PCPP-32-1) —
• Certified Professional in Python Programming 2 (PCPP-32-2) —
These certifications are progressive, meaning that you're meant to earn PCEP before PCAP (and so on), and in many cases the previous-level certificate is required to sit for the next-level certification exam.
Microsoft offers an entry-level Python certification exam called Introduction to Programming Using Python.
Data Science is now being integrated with industries across all sectors. That’s why not only are the data scientists expected to have a broader set of skills, but the employers also expect more cohesive specialization and collaboration.
Data scientists can expect to make an average of $117,345 per year. But that number can vary based on where a data scientist works, or their years of experience. For example, a data scientist working at a company with up to 500 employees can expect to earn $112,365 per year, while a data scientist with 15-plus years of experience can earn an average of $141,921 a year.
Data Science is considered one of the most lucrative jobs in the industry right now. With numerous openings spanning across all sectors, data science jobs are showing only the signs of growth. As more and more companies are adopting data science, companies are hiring data scientists by hordes. However, despite India being a frontrunner in technical education and research, the demand-supply gap for data science jobs vs applicants is only widening.
Job Roles in Data Science
• Data Analyst
• Data Engineers
• Database Administrator
• Machine Learning Engineer
• Data Scientist
• Data Architect
• Statistician
• Business Analyst
• Data and Analytics Manager
Q1. What built-in data types are used in Python?
Python uses several built-in data types, including:
Number (int, float and complex)
String (str)
Tuple (tuple)
Range (range)
List (list)
Set (set)
Dictionary (dict)
In Python, data types are used to classify or categorize data, and every value has a data type.
Q2. How are data analysis libraries used in Python? What are some of the most common libraries?
A key reason Python is such a popular data science programming language is because there is an extensive collection of data analysis libraries available. These libraries include functions, tools and methods for managing and analyzing data. There are Python libraries for performing a wide range of data science functions, including processing image and textual data, data mining and data visualization. The most widely used Python data analysis libraries include:
Pandas
NumPy
SciPy
TensorFlow
SciKit
Seaborn
Matplotlib
Q3. How is a negative index used in Python?
Negative indexes are used in Python to assess and index lists and arrays from the end, counting backwards. For example, n-1 will show the last item in a list, while n-2 will show the second to last. Here’s an example of a negative index in Python:
b = "Python Coding Fun"
print(b[-1])
>> n
Q4. What’s the difference between lists and tuples in Python?
Lists and tuples are classes in Python that store one or more objects or values. Key differences include:
Syntax – Lists are enclosed in square brackets and tuples are enclosed in parentheses.
Mutable vs. Immutable – Lists are mutable, which means they can be modified after being created. Tuples are immutable, which means they cannot be modified.
Operations – Lists have more functionalities available than tuples, including insert and pop operations and sorting.
Size – Because tuples are immutable, they require less memory and are subsequently faster.
Q5. Write a function to generate N samples from a normal distribution and plot them on the histogram.
This is a relatively simple problem. We have to set up our distribution and generate N samples from it, which are then plotted. In this question, we make use of the SciPy library which is a library made for scientific computing.
Q6. Given a list of stock prices in ascending order by datetime, write a function that outputs the max profit by buying and selling at a specific interval.
Example:
stock_prices = [10,5,20,32,25,12]
get_max_profit(stock_prices) -> 27
Making it harder, given a list of stock prices and date times in ascending order by datetime, write a function that outputs the profit and start and end dates to buy and sell for max profit.
stock_prices = [10,5,20,32,25,12]
dts = [
'2019-01-01',
'2019-01-02',
'2019-01-03',
'2019-01-04',
'2019-01-05',
'2019-01-06',
]
get_profit_dates(stock_prices,dts) -> (27, '2019-01-02', '2019-01-04')
Q7. Amy and Brad take turns rolling a fair six-sided die. Whoever rolls a “6” first wins the game. Amy starts by rolling first. What’s the probability that Amy wins?
Given this scenario, we can write a Python function that can simulate this scenario thousands of times to see how many times Amy wins first. Solving this problem then requires understanding how to create two separate people and simulate the scenario of one person rolling first each time.
Amy and Brad take turns in rolling a fair six-sided die. Whoever rolls a "6" first wins the game. Amy starts by rolling first.What's the probability that Amy wins?
Q8. Every night between 7pm and midnight, two computing jobs from two different sources are randomly started with each one lasting an hour. Unfortunately, when the jobs simultaneously run, they cause a failure in some of the company’s other nightly jobs, resulting in downtime for the company that costs $1,000.
Q9. Imagine a deck of 500 cards numbered from 1 to 500. If all the cards are shuffled randomly and you are asked to pick three cards, one at a time, what's the probability of each subsequent card being larger than the previous drawn card?
One way to start this question: Make the sample smaller. Let's say the question is actually 100 cards and you select 3 cards without replacement. Does the answer change?
