Python: Create a flat list of all the values in a flat dictionary

Python dictionary: Exercise-79 with Solution

Write a Python program to create a flat list of all the values in a flat dictionary.

  • Use dict.values() to return the values in the given dictionary.
  • Return a list() of the previous result.

Sample Solution:

Python Code:

def test(flat_dict):
  return list(flat_dict.values())
students = {
  'Theodore': 19,
  'Roxanne': 20,
  'Mathew': 21,
  'Betty': 20
}
print("\nOriginal dictionary elements:")
print(students)
print("\nCreate a flat list of all the values of the said flat dictionary:")
print(test(students))

Sample Output:

Original dictionary elements:
{'Theodore': 19, 'Roxanne': 20, 'Mathew': 21, 'Betty': 20}

Create a flat list of all the values of the said flat dictionary:
[19, 20, 21, 20]

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
