Doesn't work with other inputs

[Failton]

Hello!

With the data that I took from the webarchive, the program works fine. But if I change the input to (remove extra pairs):
{
"JPY_EUR": "0.0086356",
"EUR_JPY": "134.9401477"
}
then the program print:
No opportunity here :(

But it should print:
Starting with 100 in b'JPY'
b'JPY' to b'EUR' at 0.0086356 = 0.86356
b'EUR' to b'JPY' at 134.9401477 = 116.52891394781201

Starting with 100 in b'EUR'
b'EUR' to b'JPY' at 134.9401477 = 13494.014770000002
b'JPY' to b'EUR' at 0.0086356 = 116.52891394781201

I don't have the same problem.
But I have an issue with the b'JPY' etc, we shouldn't get that b and I can't figure why it happens.

Well, I found the solution. We have to remove the encode:

from_rate = matches.group(1).encode('ascii', 'ignore') to_rate = matches.group(2).encode('ascii', 'ignore')

from_rate = matches.group(1) to_rate = matches.group(2)
