In Python, dictionaries are a fundamental data structure used for storing key-value pairs. Searching through dictionaries can be done safely and idiomatically using built-in methods and constructs.

This guide provides a safe and idiomatic approach to searching dictionaries in Python, ensuring efficient and readable code practices.
# Example of searching a dictionary safely
my_dict = {'name': 'Alice', 'age': 30, 'city': 'New York'}
# Using the .get() method to avoid KeyError
age = my_dict.get('age', 'Not Found')
city = my_dict.get('city', 'Not Found')
print(f"Age: {age}, City: {city}")
# Using 'in' to check for existence
if 'name' in my_dict:
print(f"Name: {my_dict['name']}")
