Python for loop

Example: 6
Write a python script to display all the elements stored in the list and also print the count of all +ve elements.
Sol:

n=[23,-4,56,-7,68,-4]
p=0;
for i in n:
    print(i)
    if i>0:
        p=p+1
print("Total +ve elements in the list = ",p)

Output:

23
-4
56
-7
68
-4
Total +ve elements in the list = 3
>>>

Example: 7
Write a python script to display all the elements stored in the list and also print the count of all -ve elements.
Sol:

n=[23,-4,56,-7,68,4]
p=0
for i in n:
    print(i)
    if i<0:
        p=p+1
print("Total -ve elements in the list = ",p)

Output:

23
-4
56
-7
68
4
Total -ve elements in the list = 2
>>>

Example: 8
Write a python script to display all the elements stored in the list and also print the count of all even elements.
Sol:

n=[23,4,57,8,69,4]
p=0
for i in n:
    print(i)
    if(i%2==0):
        p=p+1
print("Total even elements in the list = ",p)

Output:

23
4
57
8
69
4
Total even elements in the list = 3
>>>

Example: 9
Write a python script to display all the elements stored in the list and also print the count of all odd elements.
Sol:

n=[23,4,57,8,69,41]
p=0
for i in n:
    print(i)
    if i%2==1:
        p=p+1
print("Total even elements in the list = ",p)

Output:

23
4
57
8
69
41
Total even elements in the list = 4
>>>

Example:10
Write a python script to display all the elements stored in the list and also print the following:
1. count of all +ve elements.
2. sum of all +ve elements
3. average of all +ve elements
Sol:

n=[1,-2,3,-4,5,-6,7,-8,-9,10]
p=0
s=0
for i in n:
    print(i)
    if(i>0):
        s=s+i
        p=p+1
print("Total +ve elements in the list = ",p)
print("sum of all +ve elements in the list = ",s)
av=s/p
print("average of all +ve elements in the list = ",av)

Output:

1
-2
3
-4
5
-6
7
-8
-9
10
Total even elements in the list = 5
sum of all +ve elements in the list = 26
average of all +ve elements in the list = 5.2
