Tuple Unpacking

Question

Hey, guys. I'm having trouble completing the task. Help please.
this is task:
Tuples can be used to output multiple values from a function.
You need to make a function called calc(), that will take the side length of a square as its argument and return the perimeter and area using a tuple.
The perimeter is the sum of all sides, while the area is the square of the side length.

Sample Input:
3

Sample Output:
Perimeter: 12
Area: 9

But i have not idea that i need to do. I have this:
def calc(x):
Perimeter = x*4
Area = x**2
return Perimeter
return Area

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))

If you know how do it? please help:3

Answer 1

First see that what is a tuple?

A Tuple is a collection of Python objects separated by commas. In someways a tuple is similar to a list in terms of indexing, nested objects and repetition but a tuple is immutable unlike lists which are mutable.

You have to make your program like this -

def calc(x):
return (x*4 , x**2)

side = int(input())
p, a = calc(side)

print("Perimeter -",p)
print("Area -",a)

Answer 2

def calc(x):
retrun(x*4,x**2)
side=int(input())
p,a = calc(side)
print("Perimeter: "+str(p))
print("Area: "+str(a))

Answer 3

My Answer:

def calc(x):
#your code goes here
return(x*4,x*x)

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))

OMG, thank you so much!

Answer 5

A Tuple is a collection of Python objects separated by commas. In someways a tuple is similar to a list in terms of indexing, nested objects and repetition but a tuple is immutable unlike lists which are mutable.

You have to make your program like this -

p, a = calc(side)

print("Perimeter -",p)
print("Area -",a)

Answer 6

but where did the 4 and 2 come from or what is their representation? how did you come to the conclusion to use return (x*4 , x*2)

Answer 7

In this case,
• perimeter (p) is the sum of all sides, in other words:
p = side*4
• area (a) is the square of the side length:
a = side**2
