Python - median value of a list

def median(x):

    if range(1, len(x))%2!=0:
        sorted(x)
        listlength = range(1, len(x)+1)
        num = listlength / 2
        middlenum = x[num]
    else:
        sorted(x)
        listlength = range(1, len(x)) 
        num = listlength / 2
        num2 = num + 1
        middlenum = x[num2 + num / 2]
    return middlenum

This is my code, I need to find a median value of a list (x) but I'm getting this error :

"Oops, try again. median([1]) resulted in an error: unsupported operand type(s) for %: 'list' and 'int' "

I don't really know what to do, please help.

Solution

  • You could also use NumPy's built-in functions, which could potentially be faster.

    import numpy as np
def median(x):
    return np.median(np.array(x))

    NumPy has a whole suite of array-based data analysis functions, such as Mean, Mode, Range, Standard Deviation and more: https://docs.scipy.org/doc/numpy/reference/routines.statistics.html

    Hope this helps!
