Is it possible to type a squared number in python?
Or how to type for example 5 to the power of 2

number**power
As Joran Beasley said you only type **2 next to the number to take it to the power of 2.
In python we multiply with * so ** is multiplying two times, which is square. however *** is an error and **3 is cubic.
however you can also define a method
def power(number,n):
x=1
for n in range(n):
x=number*x
return x
print(power(5,8))

In the formula for calculating the volume of a sphere, the radius is raised to the power of 3. So, if I assign a variable such as sphere_radius to the radius, how would I raise that variable to the power of 3 (in shorthand form without having to multiply the radius three times) in my python statement to calculate the volume?
In python, a**b will raise a to the power of b.
For example:
cubed = radius ** 3

In python
2 ** 2 ** 3 is 256
But while in mathematics getting as 64.
Use parentheses. This will give the correct answer.
(2 ** 2) ** 3
Use parentheses
x = (2**2)**3
or:
pow(2,2*3)

I was making an integer to Boolean program and was dealing with some large numbers
The test case was - 15921396743627894741911
When I used
r/2 the output was 7.960698371813948e+21
int(r/2) gave me 7960698371813947736064
and r//2 gave me 7960698371813947370955
Why is the value for the last two cases so vastly different. Thank you
In Python 3, / does "true division", which returns a float, but floats have limited precision.

I want to find the absolute value of something like 'i' but when I type 'abs(1)' it says 'i' is not defined. What do I do?
In python to find the absolute value of a complex function you use j instead of i.
abs(a+bj) # General Format
abs(0+1j)
>> 1
Or you could define i as the square root of -1 and use it instead
i = (-1) ** 0.5
abs(i)
>> 1

How come -20 % 3 = 1?
Just confused with the formulae used for negative number % positive number.
(I have seen many question related in quora but still not clear with formula used)
I am not sure about the formula but you can add x to the negative number such that (x+ negative number)>=0 and x is a multiple of mod value . This is right because
x % k = (x+ y*k) % k
