- VSMFile.swap_column(*swp, **kargs)¶
Swap pairs of columns in the data.
Useful for reordering data for idiot programs that expect columns in a fixed order.
swp (tuple of list of tuples of two elements) – Each element will be iused as a column index (using the normal rules for matching columns). The two elements represent the two columns that are to be swapped.
headers_too (bool) – Indicates the column headers are swapped as well
self – A copy of the modified
If swp is a list, then the function is called recursively on each element of the list. Thus in principle the @swp could contain lists of lists of tuples
