Python: Remove the specific item from a given list of lists
Python List: Exercise - 140 with Solution
Write a Python program to remove a specific item from a given list of lists.
Sample Solution:
Python Code:
import copy
def remove_list_of_lists(color, N):
for x in color:
del x[N]
return color
nums = [
["Red","Maroon","Yellow","Olive"],
["#FF0000", "#800000", "#FFFF00", "#808000"],
["rgb(255,0,0)","rgb(128,0,0)","rgb(255,255,0)","rgb(128,128,0)"]
]
nums1 = copy.deepcopy(nums)
nums2 = copy.deepcopy(nums)
nums3 = copy.deepcopy(nums)
print("Original list of lists:")
print(nums)
N = 0
print("\nRemove 1st item from the said list of lists:")
print(remove_list_of_lists(nums1, N))
N = 1
print("\nRemove 2nd item from the said list of lists:")
print(remove_list_of_lists(nums2, N))
N = 3
print("\nRemove 4th item from the said list of lists:")
print(remove_list_of_lists(nums3, N))
Sample Output:
Original list of lists: [['Red', 'Maroon', 'Yellow', 'Olive'], ['#FF0000', '#800000', '#FFFF00', '#808000'], ['rgb(255,0,0)', 'rgb(128,0,0)', 'rgb(255,255,0)', 'rgb(128,128,0)']] Remove 1st item from the said list of lists: [['Maroon', 'Yellow', 'Olive'], ['#800000', '#FFFF00', '#808000'], ['rgb(128,0,0)', 'rgb(255,255,0)', 'rgb(128,128,0)']] Remove 2nd item from the said list of lists: [['Red', 'Yellow', 'Olive'], ['#FF0000', '#FFFF00', '#808000'], ['rgb(255,0,0)', 'rgb(255,255,0)', 'rgb(128,128,0)']] Remove 4th item from the said list of lists: [['Red', 'Maroon', 'Yellow'], ['#FF0000', '#800000', '#FFFF00'], ['rgb(255,0,0)', 'rgb(128,0,0)', 'rgb(255,255,0)']]

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
