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

Learning objectives for this project:

• Why Python programming is awesome
• What are sets 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 dictionaries and how to use them
• When to use dictionaries versus lists or sets
• What is a key in a dictionary
• How to iterate over a dictionary
• What is a lambda function
• What are the map, reduce and filter functions

Tasks

• 0-square_matrix_simple.py

  • Write a function that computes the square value of all integers of a matrix.
  • Prototype: def square_matrix_simple(matrix=[]):
  • matrix is a 2 dimensional array
  • Returns a new matrix:
    • Same size as matrix
    • Each value should be the square of the value of the input
    • Initial matrix should not be modified
    • You are not allowed to import any module
    • You are allowed to use regular loops, map, etc.

• 1-search_replace.py

  • Write a function that replaces all occurrences of an element by another in a new list.
  • Prototype: def search_replace(my_list, search, replace):
  • my_list is the initial list
  • search is the element to replace in the list
  • replace is the new element
  • You are not allowed to import any module

• 2-uniq_add.py

  • Write a function that makes the addition of all unique integers in a list (only one time each integer).
  • Prototype: def uniq_add(my_list=[]):
  • You are not allowed to import any module

• 3-common_elements.py

  • Write a function that returns a set of common elements in two sets.
  • Prototype: def common_elements(set_1, set_2):
  • You are not allowed to import any module
