Need help (Basic python)...what did I do wrong?

[frankie_85]

Hi everyone,

I just made a simple code which is part of my assignment but I can't
figure it out what's wrong with it. (always give me error messages)

What the code basically does is:

a function that takes one floating point number x as its argument and
returns (the square root of the absolute value of x) plus (5 times x
cubed).

and read 5 floating point values from the user into a list then apply
the function to each value in the list and print the results in reverse
order.

--------------------------------------------------------------------------------------------
import math

print "Enter 5 values:"
a = float(raw_input())
b = float(raw_input())
c = float(raw_input())
d = float(raw_input())
e = float(raw_input())

def funct(a, b, c, d, e):
a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3)))
b_2 = math.sqrt(math.fabs(b)) + 5((math.pow(b,3)))
c_3 = math.sqrt(math.fabs(c)) + 5((math.pow(c,3)))
d_4 = math.sqrt(math.fabs(d)) + 5((math.pow(d,3)))
e_5 = math.sqrt(math.fabs(e)) + 5((math.pow(e,3)))
return a_1
return b_2
return c_3
return d_4
return e_5
print e_5, d_4, c_3, b_2, a_1

funct(a, b, c, d, e)
--------------------------------------------------------------------------------------------

it always gives me these error messages:

Traceback (most recent call last):
File "/Users/x/Documents/test3.py", line 25, in <module>
funct(a, b, c, d, e)
File "/Users/x/Documents/test3.py", line 11, in funct
a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3)))
TypeError: 'int' object is not callable

What did I do wrong? Please help me

Thanks in advance

You forgot the *.

obviously the error is in the line "a_1 = math.sqrt(math.fabs(a)) +
5((math.pow(a,3)))"

try changin this to "a_1 = math.sqrt(math.fabs(a)) + 5*math.pow(a,3)"

because you seem to want 5 time the result of the pow() function

hint: in most programming languages, you have to use an explicit
operator to spell out multiplication. Python's no exception.

You may want to review the restrictions your educational institution
has on collusion.

a function that takes one floating point number x as its argument
and returns (the square root of the absolute value of x) plus (5
times x cubed).

and read 5 floating point values from the user into a list then
apply the function to each value in the list and print the results
in reverse order.

--------------------------------------------------------------------------------------------
import math

print "Enter 5 values:"
a = float(raw_input())
b = float(raw_input())
c = float(raw_input())
d = float(raw_input())
e = float(raw_input())

This reads five values, but assigns five separate names to them. You
will want to review your course notes on Python to find out what a
'list' is.

it always gives me these error messages:

Traceback (most recent call last):
File "/Users/x/Documents/test3.py", line 25, in <module>
funct(a, b, c, d, e)

The error message is telling you that you have "called" an integer
('int') object. Integer objects don't support being called like
functions.

The syntax for "calling" an object is:

foo(something, something_else)

Look at the line of code reported in the error, and you'll find an
integer object being called in that fashion. You'll need to rewrite it
so it does what you're actually trying to do.

Again, please make sure you work on these problems yourself; your
assessment should not be testing your ability to ask on the internet
for assistance.

I don't think the restrictions against collusion are meant to prohibit
simple "what does this error message mean?" type questions. It would be
a funny sort of learning process that forced students to live in a
vacuum, never discussing their topic with anyone else, never asking the
most trivial questions.

I think you are wrong. The new trend is toward absolutely no instruction
at all and the students must guess the assignment. In this regard, I
believe the OP is doing very well. Don't you think?

You also may want to review what (the) return (keyword) really means.
Hopefully this will point you to the other problem in your code. ;-)

the python-tutor policy is quite reasonable:

Thanks for some of the helps guys.

Hmmm....after more trials and errors, I think what I did wrong is along
on these lines:

a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3)))
b_2 = math.sqrt(math.fabs(b)) + 5((math.pow(b,3)))
c_3 = math.sqrt(math.fabs(c)) + 5((math.pow(c,3)))
d_4 = math.sqrt(math.fabs(d)) + 5((math.pow(d,3)))
e_5 = math.sqrt(math.fabs(e)) + 5((math.pow(e,3)))

but I still don't understand though why the variable a, b, c, d, e
becomes an int type even though I have already specified the user input
to be floating point?

Once again thanks for all your help

if you want to multiply two numbers you need to put a * between them.
* is the multiplication symbol in Python and most other languages.

When you say f(x) that says "there is a function x and Python should
call it on the value x". When you say 5(x), that says "there is
a function 5 and Python should call it with the value x". And then
when you try to actually do that, Python says "hey I can't do that,
5 isn't a function, it's an integer".

hint: besides the variables, what other values are involved in your
calculations? do you see any integers among them?
