“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

Here is what works for me

    dup_count = 0
    for x in reversed(dup_list):
        dup_count += 1
        if dup_count == 1:
            print("First obj {}: {}".format(dup_count,x))
        else:
            print("Object # {}:  {}".format( dup_count,x  ))
