What is the best way to call API for each data in the list/tuple in python?

Question

I have a tuple with t = (10,20,30). I want to call an API for each of the member of this tuple t. Obviously, I can loop and call API - f("hello", b,10), f("hello",b,20), f("hello",b,20) for each item in the tuple.

However, I am looking for a best way to do this in Python.

I want to use map here or lambda. How can I do so?

How do I map with some default parameters?

Answer 1

One alternative to an explicit loop is map :

tuple(map(f, t))

# or

list(map(f, t))

This also opens the possibility to use thread or process pools for larger tasks.

Answer 2

With a for loop it's for example

for a in t:
    f("hello", b, a)

The list comprehension gives you a list as a result, which may not be what you expect:

[ f("hello", b, a) for a in t ]
