python program to find sum and product of two numbers

================================================

 

Code :

# find sum and product of two numbers

x = int(input('Enter first number:'))

y = int(input('Enter second number:'))

#display sum

print('The sum of {0} and {1} is {2}'.format(x,y,x+y))

#display product

print('The product of {0} and {1} and {2}'.format(x,y,x*y))

#display both sum and product

print('the sum of {0} and {1} is {2} and product of {0} and {1} is {3}'.format(x,y,x+y,x*y))

 

Output :

Enter first number:11
Enter second number:22
The sum of 11 and 22 is 33
The product of 11 and 22 and 242
the sum of 11 and 22 is 33 and product of 11 and 22 is 242

  Procedure to create an array using

        logspace function in python

============================================================

 

The logspace() function is somewhat similar to that

of a linspace() function .The linspace function creates

an array of evenly spaced numerical points on a linear

scale of numbers . Similarly, a logspace function can

be used to create an array of evenly spaced points but

on a logarithmic scale . Below is the expression for

usage of the logspace() function :

 

logspace(start,stop,0)

 

The logspace() function starts at a value which is 10 to

the power of 'start' and it ends at a value which is 10 to

the power of 'stop' . If 'n' is not specified , then its value

is taken by default as 50.

The arrange() function in numpy is same as range()

function in python . The arrange function is used in the

following format :

arrange(start,stop,stepsize)

This creates an array with a group of elements from 'start' to one element prior to 'stop' in steps of 'stepsize'.If the

'Stepsize' parameter is omitted , then it is taken as 1 .If the

'start' parameter is omitted ,then start is taken as 0.

np.arange(2,21,2)

output

[2,4,6,8,10,12,14,16,18,20]
