Question

17.19 Lab 8B: printing a binary number

This lab asks you to use string formatting to print a binary number. First you will prompt the user for an integer, using exactly the prompt "Enter a decimal integer: " including the colon character and a space following it. Then print out the decimal number and it's binary equivalent. You do not need to do any mathematical conversion of the integer to binary, you can use the format method.

For example, if the prompt and input are

Enter a decimal integer: 10

The output would be

10 in binary is 1010

If the prompt and input are

Enter a decimal integer: 367

The output would be

367 in binary is 101101111

If you could help me write this code in Python that would be much awesome

Answer 1

#Reading a decimal number input from user
num = eval(input("Enter a decimal integer: "))
inputNum = int(num)
#Result is used to store binary value
result = ""
#Repeat the loop till n becomes negative
while (num > 0):
    #Finding the reminder
    rem = num % 2
    #Appending reminder to the result
    result += str(rem)
    #Making num to its half
    num = num // 2
#Reverse the value of result
result = result[::-1]
#Printing final binary value to screen
print(inputNum,"in binary is",result)
