To begin it is important to know what is a dictionary, well a dictionary works similar to a list in which you can store information, but the dictionary will also organize it using this things called keys and not by order (there can’t be one key with to values, it would only save the last one). For example:
phonebook = {'Andrew Parson':8806336}
print(phonebook["Andrew Parson"])
...
8806336
Now that this is clear we need to know how to add or delete something, delete all, erase the dictionary, sort it, etc.
to delete an entry
del phonebook['Andrew Parson']
to add entries
phonebook['Sergio'] = 1234567
to change a value of an entry
phonebook['Sergio'] = 0
to erase all the entries
phonebook.clear()
to erase the hole dictionary
del phonebook
We also have build in functions to use with dictionaries, here I will write some:
len(dict)
this will give the number of items in the dictionary
str(dict)
this will transform the content in a string
dict.copy()
makes a copy from the dictionary
dict.get(key, default=None)
this will get the value assigned to a key
dict.has_key(key)
to check if a key exist, if it does return true.
dict.items()
to get tuples of all the entries in groups of key and value
dict.values()
returns a list of the values in the dictionary
sorry for the long post it has plenty information and for sure there is more so if you have more questions try this page: http://sthurlow.com/python/lesson06/
