ThePOWER function, unlike theSQRTfunction, can be used to calculate a number’s roots (such as square root or cube root) or powers (such as square or cube). ThePOWERfunction is essentially another way to do the square root, namely, raise a number to the power of 1/2. Enter the foll...
Here’s an example of a PythonValueErrorraised when trying to perform a square root operation on a negative number: importmath math.sqrt(-100)#Performing square root operation on negative number In the above example, a negative integer is passed to themath.sqrt()function. Since the function e...
Thempmathcan do large calculations using smart tricks whenever applicable. One example is factorial. For large numbers, it can use approximations appropriately without being instructed and give us the result much faster than the default Python math module. Here is what happens when we attempt to ca...

In this example, theis_primefunction checks if a number is prime by testing divisibility from 2 up to the square root of the number. Theprint_primesfunction iterates from 2 to N and prints the prime numbers. I executed the above Python code, and you can see the output in the screensho...
Let's do some manual work - type the source code. When it comes to calculate the discriminant, we have to extract a square root. There is a dedicated functionsqrtin the librarymath, but it is not yet imported. OK, let's type it anyway, and see how PyCharm copes with it. PressAl...
