Dict and enumerator object

Question

what are the different scenarios where we can use dictionary and enumerator?

Answer 1

Sahil Rana, you can use the for syntax for *any* shape of iterable, you just have to model the primary elements of that iterable correctly!

Let's say you have a list that looks like this:

list_ = [(1, (2, 3)), (4, (5, 6))]

The primary elements of the list look like this: a, (b, c)

So you can write:

for a, (b, c) in list_:
print(a, b, c)

Answer 2

Why do you place dictionaries and enum in a comparison?

Answer 3

you can enum over a dictionary to iterate over keys and/or their values.

d = {"1st":"first", "2nd":"second", "3rd":"third"}
for j in enumerate(d):
print(j[1],d[j[1]])

1st first
2nd second
3rd third

Answer 4

HonFu ,i was asking due to the fact that both objects are accessed by (for i,j in object) where i is key and j is value ,isn’t it?
