PII detection and redaction in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to detect PII entities in the text using a pre-trained model.

Prompt Engineering / GenAI

entities = model.[1](text)

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

Bfit

Ctransform

Dcompile

💡 Hint

Common Mistakes

Using 'fit' instead of 'predict' which trains the model, not detects.

The predict method is used to get the PII entities detected by the model from the input text.

2fill in blank

medium

Complete the code to replace detected PII entities with a redaction token.

Prompt Engineering / GenAI

redacted_text = text.replace(entity.value, [1])

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

A'[REDACTED]'

Bentity

Ctext

DNone

💡 Hint

Common Mistakes

Replacing with the entity itself does not redact anything.

We replace the value of the detected PII entity with the string '[REDACTED]' to hide sensitive information.

3fill in blank

hard

Fix the error in the code to correctly iterate over detected PII entities.

Prompt Engineering / GenAI

for entity in [1]:
    print(entity)

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

Centities

Dtext

💡 Hint

Common Mistakes

Looping over the raw text string instead of the entities list.

The variable entities holds the list of detected PII entities to iterate over.

4fill in blank

hard

Fill both blanks to create a dictionary mapping PII types to their counts.

Prompt Engineering / GenAI

pii_counts = {entity.[1]: pii_entities.[2](entity) for entity in pii_entities}

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

Atype

Bcount

Cindex

Dappend

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'index' or 'append' which do not count occurrences.

We use entity.type as the key and count how many times each entity appears with pii_entities.count(entity).

5fill in blank

hard

Fill all three blanks to filter PII entities by confidence score and redact them.

Prompt Engineering / GenAI

for entity in entities:
    if entity.[1] > [2]:
        text = text.replace(entity.[3], '[REDACTED]')

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

B0.8

Ctext

Dvalue

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong attribute names like 'text' instead of 'value' for replacement.

We check if the entity's confidence is above 0.8 and replace the entity's value in the text with '[REDACTED]'.
