Iterating over Dictionaries

Iterating over Keys

• The native method to iterate over a dictionary using for will iterate over keys

Example

d = {"a": 1, "b": 2, "c": 3}

for key in d:
    print(key)

Iterating over Values

• It is sometimes useful to access just values from a dictionary
• The values method can be used to get values as an iterable
• Alternatively, we can access values by their key

Example

d = {"a": 1, "b": 2, "c": 3}

for value in d.values():
    print(value)

Example

d = {"a": 1, "b": 2, "c": 3}

for key in d:
    print(d[key])

Working Problems

• Professional developers will frequently be asked to solve simple programming tasks in interviews
• It is important to practice these sorts of problems
• Example problems: LeetCode, Project Euler
