Python3

If you're a scientist or an engineer interested in learning scientific computing, this is the place to start.

In this course, you'll learn to write your own useful code to perform impactful scientific computations. Along the way, your understanding will be tested with periodic quizzes and exercises.

Topics covered in this course include arrays, plotting, linear equations, symbolic computation, scientific algorithms, and random variables. You’ll also be exposed to popular Python packages like NumPy, Matplotlib, SciPy, and others. In the last part of the course, the application section will test your ability to recall and apply the tools you have studied into newly learned scientific concepts.

At the end of this course, you'll be equipped with the tools necessary for everyday scientific computation.

Python for Scientists and Engineers

A **loop** is a control structure that is used to repeatedly execute a set of instructions. They solve the problem of having to write the same set of instructions over and over again.

There are two types of loops that we can use in Python:

* `for` loop
* `while` loop

# For loops

In a for loop, we need to define three main things:

1. The name of the iterator
2. The sequence to be traversed
3. The set of operations to be performed

``` python 3
for iterator in sequence:
    operations to be performed
```

The `in` keyword specifies that the iterator will go through the values in the sequence or data structure.

## Looping through a range
In Python, the built-in `range()` function can be used to create a sequence of integers to be iterated over in a loop. The syntax is:

```python 3
range(start, end, step)
```

The `end` value is not included in the list. If the `start` index is not specified, its default value is `0`. The `step` decides the number of steps the iterator jumps ahead after each iteration. It is optional and if we don’t specify it, the default step is 1.

In this lesson, we will learn about for and while loops in Python.
