Python – Create dictionary from the list
When it is required to create dictionary from a list, the ‘fromkeys’ method in the ‘dict’ method is used.
Example
Below is a demonstration of the same −
my_list = ['Hi', 'Will', 'how', 'Python', 'cool']
print("The list is ")
print(my_list)
my_dict = dict.fromkeys(my_list, "my_value")
print(my_dict)Output
The list is
['Hi', 'Will', 'how', 'Python', 'cool']
{'Hi': 'my_value', 'Will': 'my_value', 'how': 'my_value', 'Python': 'my_value', 'cool': 'my_value'}Explanation
A list of strings is defined and is displayed on the console.
The ‘fromkeys’ method present in ‘dict’ is used to convert the elements of the list to dictionary keys.
The value for every key is specified here itself.
This is assigned to a variable.
It is displayed as output on the console.
