Step 1: We start with an unsorted array, and we know that it splits in half until the sub-arrays only consist of one element. The Merge Sort function calls itself two times, once for each half of the array. That means that the first sub-array will split into the smallest pieces ...
concat([df1, df4], axis=1, sort=False) Warning Changed in version 0.23.0. The default behavior with join='outer' is to sort the other axis (columns in this case). In a future version of pandas, the default will be to not sort. We specified sort=False to opt in to the new ...
sort: Sort the result DataFrame by the join keys in lexicographical order. Defaults toTrue, setting toFalsewill improve performance substantially in many cases. suffixes: A tuple of string suffixes to apply to overlapping columns. Defaults to('_x','_y'). ...
