finding the second largest element from a list in python

#here n is the number of elements to be inserted in list
n=int(input('enter size of list'))
li=[]
print('enter',n,'elements in list')
for i in range(n):                #taking n input from user and storing it in list
    li.append(input())
    li[i]=int(li[i])
max=li[0]
for i in range(n):               #findingthe largest element
    if(max<li[i]):
        max=li[i]
m=li[0]
for i in range(n):             #finding the second largest element
    if(max!=li[i]):
        if(m<li[i]):
            m=li[i]
print(m)                           #printing the second largest element
