python - Access multiple values from dictionary vertically

Question

I have to fetch values from a dictionary vertically.

mydict={'a':[1,2],'b':[3,4],'c':[0,9]}
keys=list(mydict.keys())
values=list(mydict.values())

Simple Output

['a', 'b', 'c'] #keys

[[1, 2], [3, 4], [0, 9]] #values

Desired output:

def fetch_value(mydict):
   ... #do something
   return v1,v2

##output
v1=[1,3,0] 
v2=[2,4,9]

I don't want to use any for loop here as it took time and I have a very large dataset.Please suggest any faster way to do that.

Answer 1

mydict={'a':[1,2],'b':[3,4],'c':[0,9]}
print(list(zip(*mydict.values())))

output

[(1, 3, 0), (2, 4, 9)]

You can unpack the resulting list or access list elements as needed
