💡 Hint

Common Mistakes

Putting the number 10 in quotes, which makes it a string.

Using the variable name on the right side instead of a value.

The variable 'limit' should be assigned the integer value 10 without quotes.

2fill in blank

medium

Complete the code to check if the variable 'count' is greater than 5.

dbt

{% if count [1] 5 %}
  {{'Count is greater than 5'}}

💡 Hint

Common Mistakes

Using '<' which means less than.

Using '==' which means equal to.

The condition should check if 'count' is greater than 5, so use the '>' operator.

3fill in blank

hard

Fix the error in the loop to iterate over the list 'items'.

dbt

{% for item in [1] %}
  {{ item }}
{% endfor %}

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

Citem_list

Ditem

💡 Hint

Common Mistakes

Using 'item' which is the loop variable, not the list.

Using 'item_list' which is not defined.

The loop should iterate over the list named 'items'. Using 'items' is correct.

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.

dbt

{ [1]: [2] for word in words if len(word) > 3 }

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

Aword

Blen(word)

Cword.upper()

Dword.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.upper() or word.lower() as keys which changes the word.

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

The dictionary comprehension uses the word as key and its length as value.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values only if value is greater than 0.

dbt

result = { [1]: [2] for k, v in data.items() if v [3] 0 }

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

Ak.upper()

Bv

C>

Dk.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using k.lower() instead of k.upper().

Using '<' or '==' instead of '>' in the condition.

The keys are uppercase versions of k, values are v, and the condition checks if v is greater than 0.
