For Loop Dilema [python-list]

[arya . kumar2494]

Why we don’t use:

for _ in _ in _

Instead of

for _ in _:
for _ in _:

Ex:

Names = ["Arya","Pupun"]

for name in Names:
   for c in name:
   print(c)

instead use:

for c in name in Names:
print(c)

if you want to access a dict per say insisde a list or maybe some data i.e deep 
nested in some mixture of ds wont it be relevant to use a single for statement 
to query the data out.(Just a thought)
Students = [{"name":John,"age":16},{"name":Maria,"age":18}]

for info in student in Students:
 print(student[info])
