"ValueError: zero length field name in format" error in Python 3.0,3.1,3.2
I'm trying learn Python (3 to be more specific) and I'm getting this error:
ValueError: zero length field name in format
I googled it and I found out you need to specify the numbers:
a, b = 0, 1
if a < b:
print('a ({0}) is less than b ({1})'.format(a, b))
else:
print('a ({0}) is not less than b ({1})'.format(a, b))
And not like the tutorial (from lynda.com) actually says to do:
a, b = 0, 1
if a < b:
print('a ({}) is less than b ({})'.format(a, b))
else:
print('a ({}) is not less than b ({})'.format(a, b))
The tutorial im following has Python 3.1, and im using 3.2 and what i read about this error is that this only happens in <3.1 (3.0). Did they undo this in 3.2, or am i doing something wrong?
Also, speak slowly ;) this is literally my first night learning Python and only the 2nd "script" i've written in Python.
