Python: Convert a given dictionary to a list of tuples

Python dictionary: Exercise-77 with Solution

Write a Python program to convert given a dictionary to a list of tuples.

  • Use dict.items() and list() to get a list of tuples from the given dictionary.

Sample Solution:

Python Code:

def test(d):
  return list(d.items())
 
d = {'Red': 1, 'Green': 3, 'White': 5, 'Black': 2, 'Pink': 4}
print("Original Dictionary:")
print(d)
print("\nConvert the said dictionary to a list of tuples:")
print(test(d))

Sample Output: 

Original Dictionary:
{'Red': 1, 'Green': 3, 'White': 5, 'Black': 2, 'Pink': 4}

Convert the said dictionary to a list of tuples:
[('Red', 1), ('Green', 3), ('White', 5), ('Black', 2), ('Pink', 4)]

Previous: Write a Python program to combine two lists into a dictionary, where the elements of the first one serve as the keys and the elements of the second one serve as the values. The values of the first list need to be unique and hashable.
Next: Write a Python program to create a flat list of all the keys in a flat dictionary.

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")
