0x04. Python - More Data Structures: Set, Dictionary

Description

What you should learn from this project:

  • Why Python programming is awesome (don’t forget to tweet today, with the hashtag #pythoniscool :))
  • What are set and how to use them
  • What are the most common methods of set and how to use them
  • When to use sets versus lists
  • How to iterate into a set
  • What are dictionary and how to use them
  • When to use dictionaries versus lists or sets
  • What is a key in a dictionary
  • How to iterate into a dictionary
  • What is a lambda function
  • What is map, reduce and map functions

0. Squared simple

  • Write a function that computes the square value of all integers of a matrix.

1. Search and replace

  • Write a function that replaces all occurrences of an element by another in a new list.

2. Unique addition

  • Write a function that adds all unique integers in a list (only once for each integer).

3. Present in both

  • Write a function that returns a set of common elements in two sets.

4. Only differents

  • Write a function that returns a set of all elements present in only one set.

5. Number of keys

  • Write a function that returns the number of keys in a dictionary.

6. Print sorted dictionary

  • Write a function that prints a dictionary by ordered keys.

7. Update dictionary

  • Write a function that replaces or adds key/value in a dictionary.

8. Simple delete by key

  • Write a function that deletes a key in a dictionary.

9. Multiply by 2

  • Write a function that returns a new dictionary with all values multiplied by 2

10. Best score

  • Write a function that returns a key with the biggest integer value.

11. Multiply by using map

  • Write a function that returns a list with all values multiplied by a number without using any loops.

12. Roman to Integer

  • Technical interview preparation:

13. Weighted average!

  • Write a function that returns the weighted average of all integers tuple (, )

14. Squared by using map

  • Write a function that computes the square value of all integers of a matrix using map

15. Delete by value

  • Write a function that deletes keys with a specific value in a dictionary.

16. CPython #1: PyBytesObject

  • Create two C functions that print some basic info about Python lists and Python bytes objects.

Python lists:
