Python – Test if elements of list are in Min/Max range from other list

Given two lists, the task is to write a Python Program to return true if all elements from second list are in range of min and max values of the first list.

Examples:

Input : test_list = [5, 6, 3, 7, 8, 10, 9], range_list = [4, 7, 9, 6] 
Output : True 
Explanation : Min and max in list 1 are 3 and 10, all elements are in range in other list.

Input : test_list = [5, 6, 3, 7, 8, 10, 9], range_list = [4, 7, 9, 16] 
Output : False 
Explanation : Min and max in list 1 are 3 and 10, all elements are not in range in other list. 

Method #1 : Using loop + min() + max()

In this, we iterate for all the elements in second list and compare for each element, if any element is less than min or greater than max, result is flagged off and false is returned.

Python3

# Python3 code to demonstrate working of
# Min/Max range test from other list
# Using loop + min() + max()

# initializing list
test_list = [5, 6, 3, 7, 8, 10, 9]

# printing original lists
print("The original list is : " + str(test_list))

# initializing range_list
range_list = [4, 7, 9, 6]

res = True
for ele in range_list:

    # flag off list in case of any off range element
    if ele  max(test_list):
        res = False
        break

# printing result
print("Are all elements in min/max range? : " + str(res))

Output

The original list is : [5, 6, 3, 7, 8, 10, 9]
Are all elements in min/max range? : True

Method #2 : Using all() + min() + max()

In this, we check for all the elements to be in range using all(), and min() and max() are used to get the maximum and minimum elements. 

Python3

# Python3 code to demonstrate working of
# Min/Max range test from other list
# Using all() + min() + max()

# initializing list
test_list = [5, 6, 3, 7, 8, 10, 9]

# printing original lists
print("The original list is : " + str(test_list))

# initializing range_list
range_list = [4, 7, 9, 6]

# checking for all values in range using all()
res = all(ele >= min(test_list) and ele <= max(test_list)
          for ele in range_list)

# printing result
print("Are all elements in min/max range? : " + str(res))

Output

The original list is : [5, 6, 3, 7, 8, 10, 9]
Are all elements in min/max range? : True
