Dictionaries are just another data type such as lists or tuples. This dictionaries are indexed by keys, which can be any immutable type, or tuples if they don’t contain any mutable object.
You can create an empty dictionary with “{}”. You asociate key-value with “:”, separating each diferent key and value with a coma. It should look like this:
tel = {'jack': 4098, 'sape': 4139}
The dict() function can create a dictionary pairing the key value types like this:
dict([(‘sape’, 4139), (‘guido’, 4127), (‘jack’, 4098)])
{‘sape’: 4139, ‘jack’: 4098, ‘guido’: 4127}
You can access any item of a dictionarie with it’s identifyer like this:
print(dict[‘identifier1’]) #Result: “Element 1”
There are lot’s of functions you can attribute to dictionaries, some of them are str(), type(), dict.clear(), dict.copy(), dict.items(), dict.keys()… just to mention a few.
