Reorder dictionary in pyrhon according to a list of values!!!

[plomon]

Let us consider a dictionary:

sample_dict={1:'r099',2:'g444',3:'t555',4:'f444',5:'h666'}
 

I want to re-order this dictionary in an order specified by a list containing the order of the dictionary keys that I desire. Let us say the desired order list is:

desired_order_list=[5,2,4,3,1]

So, I want my dictionary to appear like this:

{5:'h666',2:'g444',4:'f444',3:'t555',1:'r099'}

How do I achieve this in the least complex way possible?

Dictionaries are in hash order always so can not be re-ordered. There is an ordered dictionary object in collections which you might want to use, or you can just use a list of tuples.

sample_dict={1:'r099',2:'g444',3:'t555',4:'f444',5:'h666'}
output_list = [(key, sample_dict[key]) for key in (5, 4, 2, 1 ,3) if key in sample_dict]
print output_list
