A Python dictionary is an unordered collection of key-value pairs. When we are working with Python dictionaries, we may sometimes need the first key of the dictionary.
So, how to get the first key of a dictionary in Python?
To get the first key of a dictionary, we can take the help of the built-in list() function. If we pass the name of the dictionary as an argument to the list() function, it will return a list containing all keys of the dictionary. Later, we can get the first key from this list by accessing its first element.
Example:
student = {
'name': 'John',
'age': 22,
'gender': 'Male'
}
all_keys = list(student)
print('All Keys: ', all_keys)
# Get the first key using all_keys[0]
print('First Key: ', all_keys[0])
Output:
All Keys: ['name', 'age', 'gender'] First Key: name
There are several other methods also which can help you to get the first key of the dictionary. But, this is the simplest method to achieve this task.
