💡 Hint

Common Mistakes

Using a variable name not matching the tuple length causes errors.

Trying to unpack into only one variable.

The tuple t has two values. We unpack them into variables a and b. So b is the correct variable name to match the second value.

💡 Hint

Common Mistakes

Using a variable name different from the one printed causes NameError.

Unpacking into fewer or more variables than tuple length causes errors.

The tuple coordinates has two values. We unpack into x and y. To print the second value, the variable must be y.

💡 Hint

Common Mistakes

Using a variable name that doesn't match the print statement causes NameError.

Unpacking into the wrong number of variables causes ValueError.

The tuple values has three elements. Unpack them into variables a, b, and c so the print statement works correctly.

4fill in blank

hard

Fill both blanks to create a dictionary with keys as names in uppercase and values as ages over 20.

Python

people = {name[1]: age for name, age in data if age [2] 20}

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

A.upper()

B>

C<

D.lower()

💡 Hint

Common Mistakes

Using < instead of > for filtering.

Using .lower() instead of .upper() for keys.

The dictionary comprehension uses name.upper() to make keys uppercase and filters ages greater than 20 using age > 20.

5fill in blank

hard

Fill all three blanks to create a dictionary with keys as uppercase names, values as ages, filtered by age greater than 25.

Python

result = [1]: [2] for name, age in people if age [3] 25}

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

Aname.upper()

Bage

C>

Dname.lower()

💡 Hint

Common Mistakes

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

Using < instead of > for filtering.

Swapping keys and values in the dictionary comprehension.

The dictionary comprehension uses name.upper() as keys, age as values, and filters ages greater than 25 with age > 25.
