dtype: int64 5. Create a Pandas Series From Python Dictionary If the dictionary object is being passed as an input and the index is not specified, dictionary keys are taken in sorted order to construct the index. If the index is passed, then values correspond to a particular label in the ...

in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
memoryview, a Cython construct for fast and bounds-safe access to a NumPy array. Another is to obtain a raw pointer to the underlying data and work with it directly, but this comes at the cost of being potentially unsafe and requiring that you know ahead of time the object’s memory ...
