EDA Python - 11-3sets

The video tutorial introduces sets in Python, highlighting their unique property of containing only unique items. It explains how to create sets using different methods, such as curly brackets and the set function. The tutorial demonstrates how sets can be used to filter unique values from lists and discusses various set operations like union and intersection, which are similar to mathematical set operations. It also covers the characteristics and limitations of sets, such as their unordered nature. Finally, the video provides resources for practicing Python set operations.

What is a key characteristic of a set in Python?

• It maintains the order of elements.

• It contains only unique items.

• It allows duplicate values.

• It is mutable.

Which of the following is a correct way to create a set in Python?

• Using angle brackets: <1, 2, 3>

• Using curly braces: {1, 2, 3}

• Using square brackets: [1, 2, 3]

• Using parentheses: (1, 2, 3)

What happens when you convert a list with duplicate values to a set?

• The duplicates are removed.

• The list is reversed.

• The list is sorted.

• The list remains unchanged.

Which operation would you use to find common elements between two sets?

• Symmetric Difference

• Difference

• Intersection

• Union

What is the result of the union operation on sets S1 = {1, 2, 3} and S2 = {3, 4, 5}?

• {1, 2, 4, 5}

• {1, 2, 3, 4, 5}

• {3, 4, 5}

• {1, 2, 3}

If S1 = {1, 2, 3} and S2 = {2, 3, 4}, what is S1 - S2?

• {1}

• {2, 3}

• {4}

• {1, 4}
