31. Get Key, Value, and Item in a Dictionary
Write a Python program to get the key, value and item in a dictionary.
Visual Presentation:
Sample Solution:
Python Code:
# Create a dictionary 'dict_num' with keys and values.
dict_num = {1: 10, 2: 20, 3: 30, 4: 40, 5: 50, 6: 60}
# Print a header for the output table.
print("key value count")
# Iterate through the key-value pairs in 'dict_num' using the 'enumerate' function.
# The 'enumerate' function assigns a count starting from 1 to each pair and unpacks them as (count, (key, value)).
for count, (key, value) in enumerate(dict_num.items(), 1):
# Print the key, value, and count in a formatted table.
print(key, ' ', value, ' ', count)
Sample Output:
key value count 1 10 1 2 20 2 3 30 3 4 40 4 5 50 5 6 60 6
