Python for loop

Example:11
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 -ve elements in the list = 5
sum of all -ve elements in the list = -29
average of all -ve elements in the list = -5.8
>>>

Example:12
Write a python script to display all the elements stored in the list and also print the following:
1. count of all even elements.
2. sum of all even elements
3. average of all even 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%2==0):
        s=s+i
        p=p+1
print("Total even elements in the list = ",p)
print("sum of all even elements in the list = ",s)
av=s/p
print("average of all even 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 even elements in the list = 30
average of all even elements in the list = 6.0
>>>

Example:13
Write a python script to display all the elements stored in the list and also print the following:
1. count of all odd elements.
2. sum of all odd elements
3. average of all odd 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%2==1):
        s=s+i
        p=p+1
print("Total odd elements in the list = ",p)
print("sum of all odd elements in the list = ",s)
av=s/p
print("average of all odd elements in the list = ",av)

Output:

1
2
3
4
5
6
7
8
9
10
Total odd elements in the list = 5
sum of all odd elements in the list = 25
average of all odd elements in the list = 5.0
>>>

Example:14
Write a python script to display all the elements stored in the list and also print the largest element?
Sol:

n=[23,4,56,7,68,4]
c=0
m=0
for i in n:
    c=c+1
    print(i)
    if(i>m):
        m=i
print("Total elements in the list = ",c)
print("Max element = ",m)

Ouput:

23
4
56
7
68
4
Total elements in the list = 6
Max element = 68
>>>

Note: If all the elements in the above program are -ve then we will get invalid output, the correct program can be modified as given below:

Modified programs:

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

Output:

-23
-4
-56
-7
-68
-4
Total elements in the list = 6
Max element = -4
>>>

Example:15
Write a python script to display all the elements stored in the list and also print the lowest element?
Sol:

n=[23,4,56,7,68,4]
c=0
m=0
for i in n:
    c=c+1
    if(c==1):
        m=i
    print(i)
    if(i<m):
        m=i
print("Total elements in the list = ",c)
print("Min element = ",m)

Output:

23
4
56
7
68
4
Total elements in the list = 6
Min element = 4
>>>

Example:16
Write a python script to display all the elements stored in the list and also print the following:
* largest element
* lowest element
* difference between largest and lowest element

Sol:

n=[10,24,33,4,15,68,10,82,19,10]
ma=0
mi=0
c=0
for i in n:
    print(i)
    if c==0:
        ma=i
        mi=i
        c=c+1
    #max no    
    if i>ma:
        ma=i
    #min no
    if i<mi:
        mi=i
print("max no = ",ma)
print("min no = ",mi)
d=ma-mi
print("diff = ",d)

Output:

10
24
33
4
15
68
10
82
19
10
max no = 82
min no = 4
diff = 78
