** Operator Typeerror

I keep getting this error message: File '/Users/SalamonCreamcheese/Documents/4.py', line 31, in testFindRoot() File '/Users/SalamonCreamcheese/Documents/4.py', l

Solution 1:

I think you have a mistake on this line:

result = (x, power, epsilon)

I suspect you want to be calling the findroot function with those three values as arguments rather than creating a tuple out of them. Try changing it to:

result = findroot(x, power, epsilon)

Solution 2:

result**power is trying to find x to the y where x = result and y = power.

Your problem is that result is a tuple. You can't raise a tuple to a power. It makes no sense...

You need to access the value inside the tuple that is supposed to be exponentiated and exponentiate that.

For instance, result[0] ** power, result[1] ** power, etc.

Solution 3:

It looks like you meant to call findRoot with the three arguments x, power, and epsilon. Try editing the line

result = (x, power, epsilon)

to be

result = findRoot(x, power, epsilon)

As that line presently is, result is not a number (which you'd want for the ** operator). result a tuple that has three different objects in it: x, power, and epsilon. You can use the ** operator on any two of the items in result but it's not defined for the tuple type.

Solution 4:

You can't apply a powers operation to a tuple. If you need to have all of the values to that power, try operating them separately.

You might need: [power**n for n in result]
