Python: Iterate over dictionaries using for loops

Python dictionary: Exercise-5 with Solution

Write a Python program to iterate over dictionaries using for loops.

Sample Solution:

Python Code:

# Create a dictionary 'd' with key-value pairs.
d = {'x': 10, 'y': 20, 'z': 30} 

# Iterate through the key-value pairs in the dictionary using a for loop.
# 'dict_key' represents the key, and 'dict_value' represents the value for each pair.
for dict_key, dict_value in d.items():
    # Print the key followed by '->' and the corresponding value.
    print(dict_key, '->', dict_value)	

Sample Output:

x -> 10
y -> 20
z -> 30

Python Code Editor:

Previous: Write a Python program to check if a given key already exists in a dictionary.
Next: Write a Python script to generate and print a dictionary that contains a number (between 1 and n) in the form (x, x*x).
