Numbers and/or letters (binary digits)

A barcode reader captures and translates the barcode into numbers and/or letters and then sends this data to a computer so that it can make sense of the data. Basically, when the reader moves past the barcode, the light on the scanner generates a pattern of on-off pulses that corresponds to the barcodes (black and white stripes). The scanner then converts these on and off pulses into binary digits and then sends them to a computer.

Following are the program in the Python Programming Language.

#declare variables and initialize to 0

s=0

n=0

avg=0

#set the infinite while loop

while(True):

#get input from the user

score=input()

#set if statement to break loop

if(score =="stop"):

break

#otherwise, perform calculation

else:

n+= 1

s=s+ int(score)

avg= s/n

#print average of the input

print ('average: ',avg)

Output:

stop

average: 50.75

Explanation:

Following are the description of the program.

Firstly, set three variable that is 's' for sum, 'n' for count and 'avg' for average and initialize them to 0.
Set the infinite while loop and inside it, set variable 'score' that get input from the user then, set the if conditional statement for break the loop, otherwise we calculate the sum of the user input and calculate its average.
Finally, we print the result with message.
