Configurare noua (How To)

The map() function applies a given function to each item of an iterable (list, tuple etc.) and returns an iterator.

def calculateSquare(n):
return n*n

numbers = (1, 2, 3, 4)
result = map(calculateSquare, numbers)

print(result)

# converting map object to set
numbersSquare = set(result)
print(numbersSquare)

Output:

<map object at 0x7f722da129e8>
{16, 1, 4, 9}
