Practice Makes Perfect - Median !

It works in spyder but not on the site - The error

Oops, try again. median([1]) resulted in an error: list indices must be integers, not float

I thought I got round this by rounding the float values ?

TY/

``````def median(imp):

imp.sort()
midindex2=[]
length = len(imp)

if length%2 != 0:
midindex = round((len(imp)-1)/2)
round(midindex)
median = imp[midindex]
return median
else:
i = (len(imp)/2)
i = round(i)-1
midindex2.append(i)
t=i
t = round(t)
midindex2.append(t)
return ((imp[midindex2[0]]+imp[midindex2[1]])/2)``````

#2

from the docs:

round(number[, ndigits])
Return the floating point value number rounded to ndigits digits after the decimal point. If ndigits is omitted, it defaults to zero

#3

As in - round(midindex,[2]) ?

#4

no, `round(midindex, 2)`. But why would you want 2 decimal numbers? The important part of the answer is here:

round clearly gives a float, not a integer, so you can't use round to solve this problem
