## Tests for Converter
Test 1 - upper case character > bin

Bin: 01100001
Test 3 - number > bin
>>> converter('2', 'bin')

Answer 1

def converter(char, base):
bases = {'hex': hex, 'bin': bin, 'dec': str, 'oct': oct}
print('%s: %s' % (base.title(), bases[base](ord(char))[2:]))
converter('A', 'hex')

参数名 char base 替换成 character number_system 不会有影响，这只是个参数名。
