This course will increase your skills to crack the data science or machine learning interview. You will cover all the most common data science and ML concepts coupled with relevant interview questions.
You will start by covering Python basics as well as the most widely used algorithms and data structures. From there, you will move on to more advanced topics like feature engineering, unsupervised learning, as well as neural networks and deep learning.
This course takes a non-traditional approach to interview prep, in that it focuses on data science fundamentals instead of open-ended questions.

In all, this course will get you ready for data science interviews. By the time you finish this course, you will have reviewed all the major concepts in data science and will have a good idea of what interview questions you can expect.

Data Science Interview Handbook

In a programming language, we sometimes need to execute statements x number of times. We don’t want to write the same programming statement x times, as doing so would make the code unreadable. Also, if we want to change something, we would have to change each block of code. That’s why looping is necessary.


<h2>Definite and indefinite iterations</h2>
Iteration can be definite or indefinite. Definite iterations are repeated a specific number of times, while indefinite iterations are repeated until a condition is met.



To determine the order of execution of statements

To simplified code by removing redundant steps

<h2> While loop </h2>

A `while` loop iterates a block until the condition remains `True`. 

The `while` loop operates using the following logic:

When the program reaches a `while` loop, the condition is checked. If the underlying condition is True, the code under the while block will be executed. After the execution of the complete block, the condition is checked again. If is True, the statement is executed again. Otherwise, the controls go to the code after the loop block.
