# Python: Check whether a specified list is sorted or not using lambda

## Python Lambda: Exercise-35 with Solution

Write a Python program to check whether a specified list is sorted or not using lambda.

Sample Solution:

Python Code :

``````def is_sort_list(nums, key=lambda x: x):
for i, e in enumerate(nums[1:]):
if key(e) < key(nums[i]):
return False
return True
nums1 = [1,2,4,6,8,10,12,14,16,17]
print ("Original list:")
print(nums1)
print("\nIs the said list is sorted!")
print(is_sort_list(nums1))
nums2 = [2,3,8,4,7,9,8,2,6,5,1,6,1,2,3,4,6,9,1,2]
print ("\nOriginal list:")
print(nums1)
print("\nIs the said list is sorted!")
print(is_sort_list(nums2))
``````

Sample Output:

```Original list:
[1, 2, 4, 6, 8, 10, 12, 14, 16, 17]

Is the said list is sorted!
True

Original list:
[1, 2, 4, 6, 8, 10, 12, 14, 16, 17]

Is the said list is sorted!
False
```

## Python: Tips of the Day

Returns all the elements of a list except the last one

Example:

```def tips_initial(lst):
return lst[0:-1]

print(tips_initial([1, 2, 3, 4]))
```
