So far, the purpose of each nested comprehension is pretty intuitive. However, there are other situations, such as flattening lists, where the logic arguably makes your code more confusing. Take this example, which uses a nested list comprehension to flatten a matrix:Python ...

Theforloop will iterate over this function starting from 1 till the number of pages+1. Since the output will be a nested list, you would first flatten the list and then pass it to the DataFrame. Finally, save the dataframe as a CSV file. ...

Specifying the Name metadata (as opposed to name, which is a keyword argument) will override the destination name of every matched file. This is applied before flattening, and so will preserve the relative path in whatever form is specified by flatten. To bypass this additional processing and ...
