Python: A bug waiting to happen.

useformatstring.py

# Oh yeah these and print anything with a __str__, right?

string_formating = 'This is not cool %s'
format_string = 'This is very cool {}'

# Wrong, wrong, wrong...

input = ('since', 'I', 'can', 'do', 'this')

print format_string.format(input)

# There is a reason this is second :)

print string_formating % input

# Of course, if we could predict the future this a new Python programmer could have done
# print string_formatin % (input,)
# But to expect that mistake to be avoided consistently, is ludicrous
