Python | Remove all sublists outside the given range
Given, list of lists and a range, the task is to traverse each sub-list and remove sublists containing elements falling out of given range.
Examples:
Input :
left= 10, right = 17, list = [[0, 1.2, 3.4, 18.1, 10.1],
[10.3, 12.4, 15, 17, 16, 11],
[100, 10, 9.2, 11, 13, 17.1], ]
Output: [[10.3, 12.4, 15, 17, 16, 11]]
Input :
left= 1, right = 9, list = [[11, 12, 15, 17, 3],
[3, 1, 4, 5.2, 9, 19],
[2, 4, 6, 7.2, 8.9]]
Output: [[2, 4, 6, 7.2, 8.9]]
Method #1 : Iterating through each sublist.
# Python code to remove all the # sublist outside the given range # Initialisation of list of listlist = [[0,1.2,3.4,18.1,10.1], [10.3,12.4,15,17,16,11], [1000,100,10,3.2,11,13, 17.1], ] # Defining rangeleft, right = 10, 17 # initialization of indexb=0 for t in list: a=0 for k in t: if k<left or k>right: a=1 if a==1: list.pop(b) b=b+1 # printing outputprint(list) |
Output:
[[10.3, 12.4, 15, 17, 16, 11]]
Method #2: Using list comprehension
# Python code to remove all the # sublist outside the given range # Initialisation of list of listlist = [[11, 12, 15, 17, 3], [3, 1, 4, 5.2, 9, 19], [2, 4, 6, 7.2, 8.9]] # Defining rangeleft = 1right = 9 # Using list comprehensionOutput = [i for i in list if (min(i)>=left and max(i)<=right)] # Printing outputprint (Output) |
Output:
[[2, 4, 6, 7.2, 8.9]]
