I have a condition for an if statement. It should evaluate to True if the user inputs either "Good!" or "Great!". The code is as follows: weather = input ("How's the weather? &

That's how it is... don't overcomplicate things by trying to simplify them. Pythonic does not mean to avoid every explicit for loop and if statement.

"In Python, you wouldn't use indexes for this at all, but just deal with the values" this statement shows you haven't done enough data analysis and machine learning modeling. Indices of one …

Actually I would do it this way: L1 is the index list of elements satisfying condition 1; (maybe you can use somelist.index(condition1) or np.where(condition1) to get L1.) Similarly, you get L2, a …

I'm an old SAS user learning Python, and there's definitely a learning curve! :-) For example, the above code could be written in SAS as: data df; set df; if A=B then C=0; else if A>B then C=1; …

You can totally do that. It's just an ordering issue: [f(x) if x is not None else '' for x in xs] In general, [f(x) if condition else g(x) for x in sequence] And, for list comprehensions with if conditions …

I did some research about functionally of contains() in especially in comparison with eq() == and found out that it can perform many tasks. I managed to answer many of them (see below). Is …

There is conditional assignment in Python 2.5 and later - the syntax is not very obvious hence it's easy to miss. Here's how you do it: x = true_value if condition else false_value For further …
