I am trying to work this out by using a dictionary that has two different details:

```
direc = {}

a = 17
b = 165
direc.update({a: b})

a = 19
b = 174
direc.update({a: b})

for x,y in direc:
    print('age:' +str(x) + ' and height :'+str(y))

```

I need the output to be:

```
age:17 and height:165
age:19 and height:174

```
