>>> import gmpy
>>> gmpy.mpz("Hello, I am a string and definitely not empy!", 10)
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
gmpy.mpz("Hello, I am a string and definitely not empy!", 10)
ValueError: invalid digits
But you don't get a TypeError, you get a ValueError. And you might
scratch your head over
>>> gmpy.mpz('zzz',26)
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
gmpy.mpz('zzz',26)
ValueError: invalid digits
until you remember that base 26 is 0-9a-p, not a-z.
