How practical do you think it would be?

Thanks for your comments. Because we find that many developers want to make their code more pythonic. And we find that many books (e.g., writing idiomatic Python) also give some guidance to help them improve their code more pythonic. For example, using truth value test, it is more concise , efficient and pythonic. Specifically,

code='''
option={}
if option!={}:
    pass
'''
code2='''
option={}
if not option:
    pass
'''

import timeit
print(timeit.timeit(code,number=1000000))
print(timeit.timeit(code2,number=1000000))
Output:
0.029162790999999966
0.018889624999999965

Although it is a small code fragment, we could see that the running efficiency also is improved.

Do you realize that your code does the opposite of the original?
