Python|删除给定范围之外的所有子列表

给定列表列表和范围，任务是遍历每个子列表并删除包含超出给定范围的元素的子列表。

例子：

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]]

方法#1：遍历每个子列表。

# Python code to remove all the 
# sublist outside the given range
  
# Initialisation of list of list
list = [[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 range
left, right = 10, 17
  
# initialization of index
b=0
  
for t in list:
    a=0
    for k in t:
        if kright:
            a=1
    if a==1:
        list.pop(b)
    b=b+1
  
# printing output
print(list)

输出：

[[10.3, 12.4, 15, 17, 16, 11]]

方法 #2：使用列表推导

# Python code to remove all the 
# sublist outside the given range
  
# Initialisation of list of list
list = [[11, 12, 15, 17, 3],
        [3, 1, 4, 5.2, 9, 19],
        [2, 4, 6, 7.2, 8.9]]
  
# Defining range
left = 1
right = 9
  
# Using list comprehension
Output = [i for i in list if (min(i)>=left and max(i)<=right)]
  
# Printing output
print (Output)

输出：

[[2, 4, 6, 7.2, 8.9]]
