Here’s a small example to demonstrate this (which only applied to DataFrames, not Series, until Pandas 0.19 where it applies to both): One solution is to sort the index first (Note: some functions require sorted indexes): Note: == is also sensitive to the order of columns, so you may have to use sort_index(axis=1): Note: This can still raise (if the index/columns aren’t … Read more

If you need to shrink and grow your list time-efficiently and without hassle, they are the way to go. But they use a lot more space than C arrays, in part because … Read more
This is called the “shape” in NumPy, and can be requested via the .shape attribute: If you prefer a function, you could also use numpy.shape(a).
it turns out I was mistaken. Solution is: in anaconda (as well as in other implementations), set the path environment variable to the directory where ‘python.exe’ is installed. As a default, the python.exe file in anaconda is in: after you do that, obviously, the python command works, in my case, yielding the following.
How can I convert a set to a list in Python? Using doesn’t work. It gives me:
