Question:1
Python program to create a list and display all the elements?
Sol:

```n=[]
while True:
a=int(input("Enter any element "))
n.append(a)
ch=input("Like to add another element ...(y/n) ")
if(ch=="y" or ch=="Y"):
continue
else:
break
print("list is ")
print(n)

```

Output:

Enter any element 2
Like to add another element …(y/n) y
Enter any element 6
Like to add another element …(y/n) y
Enter any element 8
Like to add another element …(y/n) y
Enter any element 78
Like to add another element …(y/n) y
Enter any element 25
Like to add another element …(y/n) y
Enter any element 45
Like to add another element …(y/n) n
list is
[2, 6, 8, 78, 25, 45]

Question:2
Python program to calculate and print sum of all the elements of a list?
Sol:

```n=[1,2,3,4,5]
s=0
for i in n:
print(i)
s=s+i
print("Sum of all elements ",s)
```

Output:

1
2
3
4
5

Question:3
Python program to calculate and print product of all the elements of a list?
Sol:

```n=[1,2,3,4,5]
p=1
for i in n:
print(i)
p=p*i
print("Product of all elements ",p)
```

Output:

1
2
3
4

Question:4
Python program to print total +ve elements in the list?
Sol:

```n=[1,2,-3,4,-5]
p=0
for i in n:
print(i)
if(i>0):
p+=1
print("Total +ve elements ",p)
```

Output:

1
2
-3
4
-5
Total +ve elements 3
>>>

Question:5
Python program to print total -ve elements in the list?
Sol:

```n=[1,2,-3,4,-5]
p=0
for i in n:
print(i)
if(i<0):
p+=1
print("Total -ve elements ",p)
```

Output:

1
2
-3
