Python 🐍 Dictionaries

The video tutorial covers the basics of dictionaries in Python, including how to create, manipulate, and print dictionary values. It explains how to add and modify keys, and demonstrates using loops to create and modify dictionaries. The tutorial also includes a project on using dictionaries to manage an egg incubator, showing how to set target temperatures based on animal types. The video concludes with a preview of the next lesson on data visualization.

What is the correct way to define a dictionary in Python?

• Using angle brackets with key-value pairs

• Using parentheses with key-value pairs

• Using curly brackets with key-value pairs

• Using square brackets with key-value pairs

How can you print all the keys of a dictionary?

• Using the print() function directly

• Using the values() method

• Using the keys() method

• Using the items() method

What is the correct way to add a new key-value pair to an existing dictionary?

• dictionary.append(key, value)

• dictionary.add(key, value)

• dictionary[key] = value

• dictionary.insert(key, value)

How can you handle errors when accessing a non-existent key in a dictionary?

• Using a for loop

• Using a try-except block

• Using an if-else statement

• Using a while loop

What is the purpose of using a while loop when working with dictionaries in the given context?

• To iterate over dictionary keys

• To continuously ask for user input until a condition is met

• To sort the dictionary

• To delete keys from the dictionary

How can you break out of a while loop when a specific condition is met?

• Using the break statement

• Using the exit() function

• Using the return statement

• Using the continue statement

In the context of the project, what is the role of the dictionary?

• To store key-value pairs of animal types and their target temperatures

• To store the names of animals

• To store the lifespan of each animal

• To store the number of eggs each animal lays

How can you look up a value in a dictionary using a key?

• Using the locate() method

• Using the find() method

• Using the get() method

• Using the search() method

What is the correct way to format a string in Python to include a variable?

• Using f-strings

• Using the % operator

• Using the + operator

• Using the format() method

What is the purpose of printing the keys of a dictionary in the project?

• To sort the dictionary keys

• To delete keys from the dictionary

• To check if the dictionary is empty

• To display the available options for user input
