Python: Remove a specified dictionary from a given list
Python dictionary: Exercise-48 with Solution
Write a Python program to remove a specified dictionary from a given list.
Sample Solution:
Python Code:
def remove_dictionary(colors, r_id):
colors[:] = [d for d in colors if d.get('id') != r_id]
return colors
colors = [{"id" : "#FF0000", "color" : "Red"},
{"id" : "#800000", "color" : "Maroon"},
{"id" : "#FFFF00", "color" : "Yellow"},
{"id" : "#808000", "color" : "Olive"}]
print('Original list of dictionary:')
print(colors)
r_id = "#FF0000"
print("\nRemove id",r_id,"from the said list of dictionary:")
print(remove_dictionary(colors, r_id))
Sample Output:
Original list of dictionary: [{'id': '#FF0000', 'color': 'Red'}, {'id': '#800000', 'color': 'Maroon'}, {'id': '#FFFF00', 'color': 'Yellow'}, {'id': '#808000', 'color': 'Olive'}] Remove id #FF0000 from the said list of dictionary: [{'id': '#800000', 'color': 'Maroon'}, {'id': '#FFFF00', 'color': 'Yellow'}, {'id': '#808000', 'color': 'Olive'}]

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")
