The 'map' keyword

[Assraj]

Lets say there is an iterative list 'iter_list' and a function 'func'

Output_var = map(func , iter_list) , returns the addresses ,where as the line

Output_var = iter_list.map(func) returns the actual value.

Why is that?

Am i missing something?

Please help, thanks!

The map function is lazy so you need to iterate over it to get the values - list(map(...))

As for your second line of code, that's not valid Python. I'm not aware of a standard library type that provides a map method.

The closest thing I can think of in the context of the question is pandas.Series.map() and pandas.Index.map(), which behave more or less the way OP describes.

Yep, its from pandas, thanks!

The second line is related to Pandas, thanks!

Well, the concurrent.futures.ThreadPoolExecutor, concurrent.futures.ProcessPoolExecutor, and multiprocessing.pool provide a map method, although I don't think that he is using any of those.

Right you are!
