Hi,
I am meant to design code for a program that converts from binary number to
decimal and vice versa.
This is what i have so far:
print "Welcome to the binary and decimal converter"loop = Truewhile loop:
bord = raw_input("Enter b for binary or d decimal or exit to exit") if bord
== "b": d = 0 b = 0 factor = 1; b = raw_input
("Enter Binary Number:") b=b.lstrip("0") b = int(b)
while(b > 0): if((int(b) % 10) == 1): d += factor
b /= 10 factor = factor * 2 print "The Decimal Number
is: ", d elif bord == "d": x=0 n=int(input('Enter
Decimal Number: ')) x=n k=[] # array while (n>0):
a=int(float(n%2)) k.append(a) n=(n-a)/2
k.append(0) string="" for j in k[::-1]:
string=string+str(j) print('The binary Number for %d is %s'%(x, string))
elif bord == "exit" : print "Goodbye" loop = False
- This code does not recognize invalid inputs e.g in the binary to decimal
conversion, so if I enter e.g 10021, not a binary number, it will not inform
me,the user, that the input is invalid. The same problem occurs with the
decimal to binary conversion - if i enter e.g 123&&gf I am not told to try
again with a valid input - how do I implement this in the code above
