Complete the code to define an instance method that prints the name.

Python

class Person:
    def __init__(self, name):
        self.name = name
    def show_name(self):
        print(self.[1])

💡 Hint

Common Mistakes

Using 'self' instead of 'name' inside print statement.

Using 'cls' which is for class methods.

Using 'Person' which is the class name, not an instance variable.

The instance method accesses the instance variable name using self.name.

Complete the code to define a class method that prints the class name.

Python

class Person:
    @classmethod
    def show_class(cls):
        print(cls.[1])

C__class__

D__qualname__

Attempts:

💡 Hint

Common Mistakes

Using instance variable names like 'name'.

Using __class__ which is not an attribute of cls.

Using __name__ which is a module attribute.

The class method uses cls.__qualname__ to get the class's qualified name.

Fix the error in the static method that returns a greeting string.

Python

class Person:
    @staticmethod
    def greet():
        return 'Hello, ' + [1]

Drag options to blanks, or click blank then click option'

A'World'

Cself.name

Dname

💡 Hint

Common Mistakes

Trying to access instance or class variables inside static method.

Using undefined variable 'name'.

Static methods do not receive self or cls, so use a fixed string like 'World'.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps words to their lengths only if length is greater than 3.

Python

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if [2]

Drag options to blanks, or click blank then click option'

Alen(word)

Blen(word) > 3

Cword > 3

Dword.length

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'word > 3' which compares string to number.

Using 'word.length' which is not valid in Python.

The dictionary comprehension uses len(word) for values and filters words with length greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase words to their lengths only if length is less than 6.

Python

words = ['apple', 'bat', 'carrot', 'dog']
result = [1]: [2] for word in words if [3]

Drag options to blanks, or click blank then click option'

Aword.upper()

Blen(word)

Clen(word) < 6

Dword.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.lower() instead of uppercase.

Using wrong length condition like greater than 6.

The comprehension maps uppercase words to their lengths, filtering words shorter than 6 characters.
