You need to keep track of all of the marks. Something like:

t = int(input("How many marks do you want entered" ))
g = 0

marks = []
for i in range(t):
    marks.append(int(input('what is your mark')))
g = sum(marks)/t 
print(g)

Another possibility is keeping the running sum instead of a running list, avoiding the creation of a sequence. – iz_ Feb 13 '19 at 06:23
@Tomothy32, yes of course. Integrate however you will... But Integrate you must... – Stephen Rauch Feb 13 '19 at 06:27

use below code:

t=int(input("How many marks do you want entered" ))
g=0
c=0
for i in range(t):
    c += int(input('what is your mark'))
g = c/t 
print(g)
