Python: updating values ​​in a dictionary

Question

I have the following dictionary →

key : (time,edge_list)

Now I want to increase all the time values ​​by 1. How to do this?

dict_list = dict(key:(time+1,edge_list) for key:(time,edge_list) in dict_list)

Answer 1

>>> d={"key" : (100,"edge_list")}
>>> for i,(time,edge_list) in d.items():
...  d[i] = time+1, edge_list
... 
>>> d
{'key': (101, 'edge_list')}

Answer 2

dict((key, (time + 1, edge_list)) for (key, (time, edge_list)) in somedict.iteritems())
