# Display the sum
print ('The sum of {0} and {1} is {2}'.format (numl, num2, sum))
```

Output:
Enter first number: 2.3
Enter second number: 2
The sum of 2.3 and 2 is 4.3

Program6.py:

Enter a number and display its cube value.

एक नंबर दर्ज करें और इसका घन मान प्रदर्शित करें।

```number = float (input(" Please Enter any numeric Value : "))
cube = number * number * number
print ("The Cube of a Given Number {0} = {1}". format (number, cube))
```

Output:
Please Enter any numeric Value : 3
The Cube of a Given Number 3.0 = 27.0

Example7.py:

द्विघात समीकरण हल करें

The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b and care real numbers and a ≠0

दिव्घात समीकरण का मानक रूप ह ax2 + bx+c= 0, जहाँ, a, b और c वास्तविक संख्या है औरa ≠0

```# Solve the quadratic equation ax** 2+ bx + c = 0
# import complex math module
import cmath
# To take coefficient input from the users
a = float (input ('Enter a: '))
b = float (input('Enter b:'))
c = float (input('Enter c: '))
# calculate the discriminant
d = (b** 2) - (4* a*c)
# find two solutions
soll = (-b-cmath.sqrt (d))/(2*a)
sol2 = (-b+cmath.sqrt (d))/(2*a)
print ('The solution are {0} and {1}'.format (soll, sol2))
```

Output:
Enter a: 1.2
Enter b: 2.1
Enter c: 3
The solution are (-0.8750000000000001-1.3169567191065923j) and (-0.8750000000000001+1.3169567191065923j)

Example8.py:

Find the Square Root

स्क्वायर रूट का पता लगायें

```# Note: change this value for a different result
num = float (input('Enter a number: '))
num_sqrt = num ** 0.5
print ('The square root of %0.3f is %0.3f'% (num , num_sqrt))
```

Output:
Enter a number: 9
The square root of 9.000 is 3.000

Example9.py:

Swap Two Variables

स्वैप दो वैरियेबल

```x = input ('Enter value of x: ')
y = input ('Enter value of y: ')
print ("x value : ",x, "y value : ",y)
# create a temporary variable and swap the values
temp = x
x = y
y = temp
print('The value of x after swapping: {}'.format (x))
print('The value of y after swapping: {}'.format (y))
```

Output:
Enter value of x: 10
Enter value of y: 20
x value : 10 y value : 20
The value of x after swapping: 20
The value of y after swapping: 10

Example10.py:

Without Using Temporary Variable swapping

अस्थायी वैरियेबल स्वैपिंग का उपयोग किए बिना

In python programming, there is a simple construct to swap variables.

पायथन प्रोग्रामिंग में, वैरियेबल को स्वैप करने के लिए एक सरल निर्माण ।

```a = 100
b = 20
print (a, b)
a, b = b, a
print (a, b)
```

Output
100 20
20 100

Example11.py:

print('%0.1f degree Celsius is equal to %0.1f degree Fahrenheit!' % (c, far))
```

Output :
Enter Celsius : 36.9
36.9 degree Celsius is equal to 98.4 degree Fahrenheit
