That's your mistake. Assignment is a statement not an expression. It

Why does the compiler choke on this? It seems to me that the enhanced
subtraction resolves to a legitimate integer in the exponent, but I get a
syntax error:
B = '11011101'
sum = 0
start = len(B)
for char in B:
sum += int(char) * 2**(start -= 1) ## syntax error
print(sum)
