Python Dictionary keys() Method
Returns a list of the dictionary's keys. The returned object is a "view object" - it cannot be changed.
Syntax
Python
Copy Code
dictionary.keys()
Example
Python
Copy Code
fish = {
'guppy': 2,
'zebra' : 5,
'betta': 10
}
keys = fish.keys();
print(f'My fish: {keys}')
Output
Copy Code
My fish: dict_keys(['guppy', 'zebra', 'betta'])
Notes
Often the dict_keys, a "view object", is converted to a list.
Example
Python
Copy Code
fish = {
'guppy': 2,
'zebra' : 5,
'betta': 10
}
keyList = list(fish.keys())
print(f'My fish: {keyList}')
Output
My fish: ['guppy', 'zebra', 'betta']
