Code:
a={“a”:“20”,“b”:“30”}
tuple(a[“a”])
output: ( ‘2’ , ‘0’)
why 20 split into 2 and 0.
Dictionary to (tuple or list)
Hey @Deepanshu19csu078, this is happening due to the fact that when you use tuple keyword, python by default splits a string into 2 elements. If you remove the word tuple, then the output will be 20 only. So when you mention tuple(a["a"]) , python expects to get a tuple but it just gets a 20 which it then splits into 2 and 0 to make a tuple of (‘2’ , ‘0’).
You can try this code as well :
a={"a":("20","10"),"b":"30"}
print(tuple(a["a"]))
Now since at a[“a”] there’s a tuple present , it will output the tuple itself like this without splitting anything :
('20', '10')
I hope this clears your doubt ! 
Happy Learning !
