 # Console not showing info after get_energy function

Hi,

I was trying this exercise: https://www.codecademy.com/courses/learn-python-3/projects/physics-class and as soon as I added the get_energy function at step 9 and 10, nothing was getting printed to the console anymore.
I tried putting some older functions in comments, but that wouldn’t work either, but when I comment the get_energy related things, all the others would print again.

Also the save button seems to spin for a very long time when I click it with this function being active. So maybe it’s a performance issue because it generates such a big number?

Here’s my code:

``````def f_to_c(f_temp) :
c_temp = (f_temp - 32) * 5/9
return c_temp

def c_to_f(c_temp) :
f_temp = c_temp * (9/5) + 32
return f_temp

def get_force(mass, acceleration) :
return mass * acceleration

def get_energy(mass, c = 3*10**8) :
return mass * c**c

train_mass = 22680
train_acceleration = 10
train_distance = 100

bomb_mass = 1

f100_in_celsius = f_to_c(100)
c0_in_fahrenheit = c_to_f(0)
train_force = get_force(train_mass, train_acceleration)
bomb_energy = get_energy(bomb_mass)
print(f100_in_celsius)
print(c0_in_fahrenheit)
print(train_force)
print("The GE train supplies " + str(train_force) +" Newtons of force.")
print("A 1kg bomb supplies " + str(bomb_energy) + " Joules.")

``````

I think it’s a rather intense calculation which is taking all that time to compute. However, this should probably be c**2?
c ** c is a bit much eh?

Thanks! that was it!

I translated squared wrong apparently it should be c*c of course or c**2 as you said. Mistook it for the exponent of itself.
