d1 = (np.log(S0/K) + (r + sigma**2 / 2) * T)/(sigma * np.sqrt(T))
TypeError: unsupported operand type(s) for /: 'int' and 'str'
which I just don't understand because i forced my inputs to be a float and therefor this shouldn't give me an error.
Can somebody help me here out?
The function does work if I define values instead of reading them from the bash.
