Get the arithmetic mean of the elements on the even and odd positions.

What I have tried:

import random
a=input
s=0
x=0
l=random.sample((1,30),a)
for i in range(1,a+1) :
   if i %2 ==0 :
        s+=s+element
        r+=1
   else :
        x+=x+element
        t+=1
o=s/r
print o
z=x/t
print z

Solution 1

Where did you get this code from? You have no clue about it. For example:
1. what is

a=input

?
2. what is

random.sample((1,30),a)

?
3. what is

element

?
4. Many more syntax and logical errors...
You really have to start to Learn Python[^] properly. BTW, ditch Python 2, go for Python 3.
