“For” loop first iteration

Question

I would like to inquire if there is an elegant pythonic way of executing some function on the first loop iteration. The only possibility I can think of is:

f         


        

Answer 1

This works:

for number, member in enumerate(something.get()):
    if not number:
        root.copy(member)
    else:
        somewhereElse.copy(member)
    foo(member)

In most cases, though, I'd suggest just iterating over whatever[1:] and doing the root thing outside the loop; that's usually more readable. Depends on your use case, of course.
