write a program to take a tuple of numbers from the keyboard and print sum ,avg

a=eval(input("Enter  some of tuple numbers"))
l=len(a)
sum=0
for x in a:
    sum=sum+x
print("The sum=",sum)
print("The avg=",sum/l)

output:
Enter  some of tuple numbers(10,20,30)
The sum= 60
The avg= 20.0

Tuple comprehension not support in python

a=(x*x for x in range(1,11))
#print(a)
for x in a:
    print(x)

output:
1
4
9
16
25
36
49
64
81
100

Write a program for tuple packing in python

Tuple packing:
====================================

t=(10,20,30,40)
a,b,c,d=t
print("a=",a,"b=",b,"c=",c,"d=",d)

output:
a= 10 b= 20 c= 30 d= 40



Tuple packing for strings:
==============================
t="abcd"
a,b,c,d=t
print("a=",a,"b=",b,"c=",c,"d=",d)

output:
a= a b= b c= c d= d

Perform Addition, Subtraction, Multiplication, Division and Modulus operation on two integers.

#include<stdio.h>

void main()

{ int a,b;

printf("\n enter two values: ");

scanf("%d %d",&a,&b);

printf("\n a + b = %d", a+b);

printf("\n a - b = %d", a-b);

printf("\n a * b = %d", a*b);

printf("\n a / b = %d", a/b);

printf("\n a modulus b = %d", a%b);

getch();

}

input:

 enter two values: 13  5

output:

 a + b = 18           

 a - b = 8

 a * b = 65

 a / b = 2

 a modulus b = 3

MM32f103 led blink program

To work on mind motion MM32 microcontroller we need to install the keil uvision 5 version
then install the mm32-link programmer

go to library folder their you will get the
MM32F103_library_examples\MM32F103xx_m_Lib_Samples_V1.01_SC\MM32F103RegLibMB_Ver1.9.5\Boards_MM32x103\MB103CBT6_lib\BLINK\IOToggle\KEIL_PRJ

open the file in keil. options target  their to need to do mm32-ulink.

finding the length of tuple in python

t1=(10,20,30)
print(len(t1))

output:
3

multiplication of Tuple in python

t1=(10,20,30)
t2=t1*2
print(t2)


output:
(10, 20, 30, 10, 20, 30)

example 2:


t1=(10,20,30)
t2=t1*3
print(t2)

output:
(10, 20, 30, 10, 20, 30, 10, 20, 30)

addition of Tuple in python

t1=(10,20,30)
t2=(40,50,60)
t3=t1+t2
print(t1)
print(t2)
print(t3)

output 1:
(10, 20, 30)
(40, 50, 60)
(10, 20, 30, 40, 50, 60)
