**While** loop is another type of loops. It performs the same, but the construction of the loop differs.

# Summing all prices
prices = [3, 5, 6, 2, 7, 8]
i = 0
counter = 0

while i < len(prices):
  counter += prices[i]
  i += 1

print(counter)

When we want to stop our loop immediately, we need to use `break.`

prices = [1, 2, 3, 4, 5, 6]
i = 0

while i < len(prices):
  if prices[i] == 4:
    break
  else:
    print(prices[i])
  i += 1

> We use a special variable (``counter`` in our case) to collect elements of the price list (in our case). If you want to count the sum of the numbers from 1 to 10, you also have to create a variable that collects the sum after each iteration.

This course will teach you the necessary skills to manage simple analytical tasks. You are going to learn Python and its libraries, such as pandas and NumPy. Besides, you will deal with real-life analytical tasks such as calculating vitally important marketing metrics.

Here, we will face challenges related to data types in python. In this section, we will learn the Python syntax necessary for each person who wants to work with this language. After the section, we will undoubtedly be able to cope with simple Python tasks.

This section will teach you simple Python functions. We will be able to work with if/else statements and loops. Such skills are necessary for everyone who wants to start programming and doing fascinating Python tasks.

This section is the most complicated than the previous one, but it is gripping. Here, we will manage the most commonly used pandas function to help we do essential operations with data. Also, we will learn the basics of the NumPy library.

This section allows you to become a real analyst. Let's go!
