Handling data from multiple dictionaries in a single variable

Question

Beginner question but I wanted to handle data from multiple dictionaries in a single variable. For example:

x = {"age":"24","name":"Bob"}, {"age":"21","name":"George"}

In this case, how would I find out what "age" is in each dictionary in x, and put them in a list? This should be the desired outcome:

ages = ["24","21"]

This is what I've tried so far but raises an error:

x = {"age":24,"name":"Bob"}, {"age":21,"name":"George"}
ages = []
for y in x:
     ages.append(x["age"])

TypeError: list indices must be integers or slices, not str

Answer 1

Use ages.append(y["age"]) - note the y which references each dictionary in the tuple of dictionaries referenced by x

Answer 2

Maybe because you try and find the key of a tuple? You need to use y.

ages = []
for y in x:
     ages.append(y["age"])
print(ages)

Answer 3

You can just check whether the dictionary contains the key you want.

if "age" in y:
    ages.append(y["age"])
