I want to create sub-lists from a list which has many repeating elements, ie. A split function can be a very handy Python function when working on a text mining project. Python Because the number of dimensions can vary, you may implement a generic solution with the help of the starmap() and product() functions from the itertools module: This function yields objects of a custom Bounds type, which allows you to retain the spatial information of each chunk regardless of the number of dimensions. Python String split(): List, By Character, Delimiter EXAMPLE - Guru99 In case the max parameter is not specified, the split() function splits the given string or the line whenever a separator is encountered.
