why i$\text{'}$m not getting any output from this path: my$\_$results, A$01\_$Part$1$: result.txt$.$

Technology:

Python $($without using the MapReduce simulator$).$

Your task is to:

$$ Compute the top$\_$n$\_$bikes with highest total duration time for their trips.

Complete the function my$\_$main of the Python program.

o Do not modify the name of the function nor the parameters it receives.

o In particular, the function must read the dataset provided in input$\_$folder and must open

and write the results to output$\_$file. The number of bikes to output is specified by the

parameter top$\_$n$\_$bikes. For example, if top$\_$n$\_$bikes $=10,$ then you must output the $10$

bikes with highest total duration time for their trips.

o You can use the auxiliary function process$\_$line which, given one line from a dataset

file, returns a tuple with its content.

o You can also program any other auxiliary functions you might need.

Results:

Output one text line per bike$\_$id$.$ Lines must follow decreasing order in highest total duration

time for their trips. Each line must have the following format:

bike$\_$id $\backslash$t $($total$\_$duration$\_$time$\_$for$\_$their$\_$trips, total$\_$number$\_$of$\_$trips$)$
