How can I print two return values using .format()?

I am creating a function to find the min and max of a dataset, and I get an error when I try to use two return values. I cannot figure out how to format the print function to accept two values that are in the same function.

CODE:

data=[1,5,3,8,9,7,2]

def minMaxList(data):
    min=data[0]
    max=data[-1]
    for i in data:
        if i>max:
            max=i
        if i<min:
            min=i
    return (min, max)   

print("The min and max of this population is {:.2f} and {:.2f}".format(minMaxList(data)))

ERROR:

Type Error: unsupported format string passed to tuple.__format__

val = minMaxList(data)
print("The min and max of this population is {} and {}. format (val[0], val[1])

You need to use unpacking operator * So your code should look like

print("The min and max of this population is {:.2f} and {:.2f}".format(*minMaxList(data)))

Your code snippet:

data=[1,5,3,8,9,7,2]
def minMaxList(data):
    min=data[0]
    max=data[-1]
    for i in data:
        if i>max:
            max=i
        if i<min:
            min=i
    return (min, max)
print("The min and max of this population is {:.2f} and {:.2f}".format(minMaxList(data)))

Here you get an issue because the function minMaxList() returns a tuple/iterative object which needs to be unpacked to resolve issue here, to do this

use * before function call, the print statement should be:

print("The min and max of this population is {:.2f} and {:.2f}".format(*minMaxList(data)))

Output Looks like this

You can just add an asterisk (*) before the tuple to unpack it:

print("The min and max of this population is {:.2f} and {:.2f}".format(*minMaxList(data)))

with this addition the program outputs:

The min and max of this population is 1.00 and 2.00

Alternatively,

min, max = minMaxList(data)
print("The min and max of this population is {:.2f} and {:.2f}".format(min, max))

gives the same output and may be more readable.
