Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if any number in the list is greater than 5 using the any() function.

Python

numbers = [1, 3, 7, 2]
result = any(num [1] 5 for num in numbers)
print(result)

💡 Hint

Common Mistakes

Using '<' instead of '>' which checks for smaller numbers.

Using '==' which checks for equality, not greater than.

The any() function returns True if at least one element in the iterable is True. Here, we check if any number is greater than 5.

medium

Complete the code to check if all numbers in the list are positive using the all() function.

Python

numbers = [4, 6, 8, 1]
result = all(num [1] 0 for num in numbers)
print(result)

💡 Hint

Common Mistakes

Using '<' which checks if numbers are less than zero.

Using '==' which checks for equality, not positivity.

The all() function returns True only if every element in the iterable is True. Here, we check if all numbers are greater than 0 (positive).

Fix the error in the code to correctly check if any word in the list starts with the letter 'a'.

Python

words = ['apple', 'banana', 'cherry']
result = any(word.[1]('a') for word in words)
print(result)

💡 Hint

Common Mistakes

Misspelling the method name as 'startwith' or 'starts_with'.

Using a non-existent method like 'start'.

The correct method to check if a string starts with a specific character is startswith(). Other options are incorrect method names.

4fill in blank

hard

Fill both blanks to create a dictionary of words and their lengths, but only include words longer than 3 characters.

Python

words = ['cat', 'elephant', 'dog', 'lion']
lengths = {word: [1] for word in words if len(word) [2] 3}
print(lengths)

💡 Hint

Common Mistakes

Using '<=' instead of '>' which includes shorter words.

Using 'word' instead of 'len(word)' for the dictionary value.

We use len(word) to get the length of each word. The condition len(word) > 3 filters words longer than 3 characters.

5fill in blank

hard

Fill both blanks to create a dictionary with uppercase words as keys and their lengths as values, including only words with length greater than 4.

Python

words = ['tree', 'mountain', 'river', 'sky']
result = {word.[1](): [2] for word in words if len(word) > 4}
print(result)

💡 Hint

Common Mistakes

Using square brackets instead of curly braces for the dictionary.

Forgetting to call the upper() method with parentheses.

Using 'word' instead of 'len(word)' for the value.

The dictionary is created using curly braces {}. We convert words to uppercase with upper() and get their lengths with len(word). The condition filters words longer than 4 characters.
