How to print a dictionary's key in python?

To print all the keys of a dictionary in Python, you can use a simple loop or list comprehension. Here are a couple of examples:

  • Using a loop:
my_dict = {'key1': 42, 'key2': 'value', 'key3': [1, 2, 3]} # Iterate through the keys and print them for key in my_dict: print(key)
  • Using list comprehension:
my_dict = {'key1': 42, 'key2': 'value', 'key3': [1, 2, 3]} # Use a list comprehension to get all keys and then print them keys = [key for key in my_dict] print(keys)

Both of these approaches will give you a list of the dictionary's keys, which you can then print or manipulate as needed.
