💡 Hint

Common Mistakes

Initializing token_count to None or an empty string instead of zero.

We start counting tokens from zero, so initializing token_count to 0 is correct.

💡 Hint

Common Mistakes

Using subtraction or multiplication instead of addition.

We add the tokens used in the current step to the total token_count using '+='.

3fill in blank

hard

Fix the error in the code to calculate the cost based on tokens used and price per token.

Agentic AI

cost = tokens_used [1] price_per_token

💡 Hint

Common Mistakes

Using addition or division instead of multiplication.

Cost is calculated by multiplying tokens used by price per token, so '*' is correct.

4fill in blank

hard

Fill both blanks to create a dictionary that tracks tokens and cost for each step.

Agentic AI

usage = {'tokens': [1], 'cost': [2]

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

💡 Hint

Common Mistakes

Mixing total_cost with cost for the current step.

The 'tokens' key should hold tokens_used, and 'cost' should hold the calculated cost.

5fill in blank

hard

Fill all three blanks to update total tokens, calculate cost, and store usage info.

Agentic AI

token_count [1]= tokens_used
cost = tokens_used [2] price_per_token
usage = {'tokens': tokens_used, 'cost': [3]

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

💡 Hint

Common Mistakes

Using wrong operators or storing wrong values in usage.

We add tokens_used to token_count, multiply tokens_used by price_per_token for cost, and store cost in usage.
