To handle cases where response.tokens_info might be empty or contain multiple elements, consider summing the token counts from all TokensInfo objects within response.tokens_info for a more robust approach.

print(f"token count: {sum(len(info.tokens) for info in response.tokens_info)}")

I agree that the suggestion is more approach but this is a pretty simple example. I don't think we need to complicate it with the fully robust solution. The goal here is to understand basic usage.

@kaycebasques could you update the approach so that it does handle an empty response? The basic usage is the goal, and if it fails for whatever reason having the sample address it encourages the recommended practice.

# Example output:
# tokens_info=[TokensInfo(
# role='user',
# token_ids=[1841, 235303, 235256, 573, 32514, 2204, 575, 573, 4645, 5255, 235336],
# tokens=[b'What', b"'", b's', b' the', b' longest', b' word', b' in', b' the', b' English', b' language', b'?']
# )]
# token count: 11
# [END googlegenaisdk_counttoken_compute_with_txt]
return response.tokens_info
