I got an answer but the system rated my answer below 60%-CodePudding

I was given a task to "Create a function with two parameters a and b. The function calculates the following expression: (12 * a 25 * b) / (1 a**(2**b)) and returns a result of the expression rounded up to the second decimal place.

but after writing my code I got a grade below 60%. I don't know what is wrong with my code

Here is my code:

a = 4
b = 5
result = (12 * a   25 * b) / (1   a ** (2 ** b))
print(result)
print("The value is: ", 9.378348791999613e-18)
print("The value rounded to 2 decimal place: ", round(9.378348791999613e-18, 2))

There are a few potential issues with your code:

You are not defining the function with the two parameters, a and b. Instead, you are hardcoding the values for a and b and then calculating the result. To make the function work as intended, you need to define it as follows:

def expression(a, b):
  result = (12 * a   25 * b) / (1   a ** (2 ** b))
  return round(result, 2)

The print statement that outputs the result rounded to 2 decimal places is not correct. You are printing the result of the calculation, not the result rounded to 2 decimal places. To fix this, you can use the round function to round the result before printing it. For example:

print("The value rounded to 2 decimal places: ", round(result, 2))

You are using scientific notation (e-18) to display the result, which may not be what the task is asking for. To avoid this, you can use the format function to specify the number of decimal places you want to display. For example:

print("The value rounded to 2 decimal places: {:.2f}".format(result))

To test the function using different values of a and b:

print("The value for a=4 and b=5 is: {:.2f}".format(expression(4, 5)))
print("The value for a=7 and b=3 is: {:.2f}".format(expression(7, 3)))
print("The value for a=2 and b=6 is: {:.2f}".format(expression(2, 6)))

Due to you need to use a function but your code not using function

Ex:

def sum(var_one, var_two):
    result = (12 * var_one   25 * var_two) / (1   var_one ** (2 ** var_two))
    print("The value is: ", result)
    print("The value rounded to 2 decimal place: {:.2f}".format(round(result, 2)))

sum(4, 5)
