dict ={'A':{'x':'123','y':'322','z':'432'},'B':{'x':'24','y':'622','z':'5652'},'C':{'x':'424','y':'682','z':'52'},'D':{'x':'32','y':'96','z':'3'}}
arr1 = ['A','B','D']
values of key to changed: y,z
I want to change dict value(x,y) based on arr1
such that value of ‘y’ should be equal to ‘z’
Required Dict
dict ={'A':{'x':'123','y':'322','z':'322'},'B':{'x':'24','y':'622','z':'622'},'C':{'x':'424','y':'682','z':'52'},'D':{'x':'32','y':'96','z':'96'}}

Answer
Try:
You can you can iterate over the elements of arr1
then set the value of the z
key.
dict1 ={'A':{'x':'123','y':'322','z':'432'},'B':{'x':'24','y':'622','z':'5652'},'C':{'x':'424','y':'682','z':'52'},'D':{'x':'32','y':'96','z':'3'}} arr1 = ['A','B','D'] for i in arr1: dict1[i]['z']=dict1[i]['y'] print(dict1)
PS: Don’t use keywords like dict
as variables because they shadow the inbuilt functions
