Factorial

Answer 2

No one who keeps you from doing this. the function needs 2 lines of code and the call 1 line. so it’s 3 lines in total. you should be able to do this by yourself.

Answer 3

Square root can be calculated by the formula: n to the power of 0.5. so if you want to get the square root of 49 you can use this expression:

print(49 ** 0.5)

# output is 7.

Answer 4

I want to define a function not to just get that value.
