Python fromkeys() Function
The fromkeys() function in Python is used to create a dictionary using specified keys and value. For example:
k = ("one", "two", "three") v = 100 dOne = dict.fromkeys(k, v) print(dOne) dTwo = dict.fromkeys(k) print(dTwo)
The output will be:
{'one': 100, 'two': 100, 'three': 100} {'one': None, 'two': None, 'three': None}
Python fromkeys() Function Syntax
The syntax of fromkeys() function in Python is:
dict.fromkeys(keys, value)
where keys refers to an iterable that specifies the keys, whereas value refers to a value to set for all the keys.
Note - The first parameter (keys) is required, whereas the second parameter (value) is optional.
Python fromkeys() Function Example
Here is an example of fromkeys() function in Python.
d = dict.fromkeys([12, 432, 45, 5, 6, 34]) print(d)
The output will be:
{12: None, 432: None, 45: None, 5: None, 6: None, 34: None}
