print(first_key)print first dictionary keys python
first_key = list(my_dict.keys())[0]
print(first_key)python return first n key values pairs from dictionary
# Basic syntax:
{key: dictionary[key] for key in list(dictionary)[:number_keys]}
# Note, number_keys is the number of key:value pairs to return from the
# dictionary, not including the number_keys # itself
# Note, Python is 0-indexed
# Note, this formula be adapted to return any slice of keys from the
# dictionary following similar slicing rules as for lists
# Example usage 1:
dictionary = {'a': 3, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
{key: dictionary[key] for key in list(dictionary)[:2]}
--> {'a': 3, 'b': 2} # The 0th to 1st key:value pairs
# Example usage 2:
dictionary = {'a': 3, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
{key: dictionary[key] for key in list(dictionary)[2:5]}
--> {'c': 3, 'd': 4, 'e': 5} # The 2nd to 4th key:value pairspython get first value in a dictionary
# Dictionary of string and int
word_freq = {
'Hello' : 56,
"try" : 23,
'test' : 43,
'This' : 78,
'Way' : 11
}
# Get first value from dictionary
first_value = list(word_freq.values())[0]
print('First Value: ', first_value)
# Output:
# First Value: 56Copyright © 2021 Codeinu
