💡 Hint

Common Mistakes

Trying to use a variable name that is not defined.

Using the keyword 'global' instead of the variable name.

The variable count is defined outside the function, so it is a global variable. To access it inside the function, just use its name count.

💡 Hint

Common Mistakes

Forgetting to declare the variable as global before modifying it.

Using a different variable name in the global statement.

To change a global variable inside a function, you must declare it as global followed by its name. Here, the global variable is score.

💡 Hint

Common Mistakes

Using a capitalized variable name Name which is undefined.

Trying to print the string "name" instead of the variable.

The variable name is global and should be used exactly as defined. Variable names are case-sensitive, so Name is different and undefined.

Fill both blanks to create a dictionary with word lengths only for words longer than 3 letters.

Python

words = ["apple", "cat", "banana", "dog"]
lengths = {word: [1] for word in words if len(word) [2] 3}
print(lengths)

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

💡 Hint

Common Mistakes

Using the word itself instead of its length.

Using less than symbol which filters shorter words.

The dictionary comprehension uses len(word) to get the length of each word. The condition len(word) > 3 filters words longer than 3 letters.

Fill all three blanks to create a dictionary with uppercase keys and values only for positive values.

Python

data = {"a": 1, "b": -2, "c": 3}
result = { [1]: [2] for k, v in data.items() if v [3] 0 }
print(result)

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

💡 Hint

Common Mistakes

Using the original key without uppercase.

Filtering values less than or equal to zero.

The dictionary comprehension uses k.upper() to make keys uppercase, keeps values v, and filters only positive values with v > 0.
