Python Python Collections (2016, retired 2019) Tuples Introduction To Tuples

Need help.

So, I don't know why this wasn't working for me. but I've tried many ways.

def dicts():
    tuple_dict = ({"name": "jassim", 
               "num": 200,
               "siblings":{"name":"noor",
                           "name2":"Jacob"}
              })

I want it to print out the keys at first then the values. Separate lines.

It's probably an easy answer but I'm bad with def, So thank you.

Hi Jassim, using the methods .keys() will get the keys of a dictionary, .values() will get the dictionary values, and .items() will get the key / value pairs returned as a tuple.

The tuple_dict in your code is actually just a dict. Wrapping an object in parens will not make it a tuple. If you use a comma after the first item then a tuple is created: (item, )

So for a given dictionary you can use:

for key in some_dict.keys():
    print(key)
for value in some_dict.values():
    print(value)
for key, value in some_dict.items():
   print(key, value)

Post back if you need any more help. Good luck!!
