Why does my code have error ??

Question

Hi can you tell me why is my this code isn't working??

# Input 0 for binary to int or 1 for int to binary
# Then input your number
a = int(input ())
if a == 0:
b = bin (input ())
b = str (int (b))
print (b[2:-1], b[-1])
elif a == 1:
c = int (input ())
c = str (bin (b))
print (c[2:-1], c[-1])

Answer 1

the code can be done a bit shorter, also there are some issues:

a = int (input ())
if a == 0:
print(int(input(),2))
elif a == 1:
print(bin(int(input()))[2:])

Answer 2

In 6 line use bin(int(input()))
