Hello Python wizards out there, hope you all are doing well!

I just took birth in python world a few months ago so please pardon my lack of knowledge here. I am trying to do basic multiplication within all the individual elements of this list but where am I going wrong with using lambda expression here?

inputData = [[2,3], ["4", 7], [6,4], [222, 25, 7],["16",22,"12", 6]]

code I wanted to replicate:

for element in inputData:
    value = 1
    for multi in element:
        if isinstance(multi, str):
            multi = int(multi)
        value = value*multi
    print(value)

Code I am trying:

for element in inputData:
    value = 1
    for multi in element:
        multiplication = lambda multi: int(multi)*value if isinstance(multi, str) == True else 
        multi*value
    print(multiplication(inputData))
