Answer 
In Python, the keys() method is used to get a list of all the keys in a dictionary. Here's an example:
my_dict = {'a': 1, 'b': 2, 'c': 3}
keys_list = my_dict.keys()
print(keys_list) # output: ['a', 'b', 'c']
In this example, my_dict.keys() returns a list of all the keys in the my_dict dictionary, which are then assigned to the keys_list variable. The print() function is used to display the contents of the keys_list variable.
Note that the keys() method returns a view object in Python 3.x, which is a dynamic view on the dictionary's keys that reflects any changes to the dictionary. In Python 2.x, keys() returns a list of the dictionary's keys.
You can use the keys() method to iterate over the keys of a dictionary using a for loop, like this:
my_dict = {'a': 1, 'b': 2, 'c': 3}
for key in my_dict.keys():
print(key)
This will print out each key in the my_dict dictionary on a separate line.

In Python, .keys() is a method that can be used on a dictionary object to return a view object containing the keys of the dictionary. Here's an example of how to use it:
# Create a dictionary
my_dict = {'name': 'John', 'age': 25, 'gender': 'Male'}
# Get a view object containing the keys of the dictionary using .keys()
keys = my_dict.keys()
# Print the view object
print(keys)
Output:
dict_keys(['name', 'age', 'gender'])
