Predict the output of following code if the input is :

(i) 12, 3, 4, 5, 7, 12, 8, 23, 12

(ii) 8, 9, 2, 3, 7, 8

Code :

s = eval(input("Enter a list : "))
n = len(s)
t = s[1:n-1]
print(s[0] == s[n-1] and
t.count(s[0]) == 0)

Predict the output :

def h_t(NLst):                
    from_back = NLst.pop()            
    from_front = NLst.pop(0)
    NLst.append(from_front)
    NLst.insert(0, from_back)
NLst1 = [[21, 12], 31]
NLst3 = NLst1.copy()
NLst2 = NLst1
NLst2[-1] = 5
NLst2.insert(1, 6)
h_t(NLst1)
print(NLst1[0], NLst1[-1], len(NLst1)) 
print(NLst2[0], NLst2[-1], len(NLst2)) 
print(NLst3[0], NLst3[-1], len(NLst3))

Predict the output :

L1= [x ** 2 for x in range(10) if x % 3 == 0]
L2 = L1
L1.append(len(L1))       
print(L1)
print(L2)      
L2.remove(len(L2) - 1) 
print(L1)

Predict the output :

def even(n):
    return n % 2 == 0
list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9]
ev = [n for n in list1 if n % 2 == 0]
evp = [n for n in list1 if even(n)]
print(evp)
