Easy ⏱ 8 min 77% acceptance ★★★★★ 4.5

Implement pack_reading(temperature, humidity, pressure) that packs the three arguments into a single tuple and returns it. Then implement unpack_reading(reading) that unpacks such a tuple into three named variables in one line and returns a formatted string.

Examples

Example 1

Input

pack_reading(24.5, 60, 1013)

Output

(24.5, 60, 1013)

Explanation

Three values packed into one tuple.

Example 2

Input

unpack_reading((24.5, 60, 1013))

Output

'24.5C, 60%, 1013hPa'

Explanation

Tuple unpacked into temp, hum, pressure in a single assignment.

Constraints

unpack_reading must use tuple unpacking, not reading[0]/reading[1]/reading[2] indexing.
