list=[] n=int(input()) for i in range(n): p=input().split() if p[0]=="insert": list.insert(int(p[1]),int(p[2])) elif p[0]=="print": print(list) elif (p[0]=="remove"): list.remove(int(p[1])) elif p[0]=="append": list.append(int(p[1])) elif p[0]=="sort": list.sort() elif p[0]=="print": print(list) elif p[0]=="pop": list.pop() elif p[0]=="reverse": list.reverse() elif p[0]=="print": print(list)

Initialize your list and read in the value of n followed by n lines of commands where each command will be of the 7 types listed above. Iterate through each command in order and perform the corresponding operation on your list.

N = int(input('Number of commands You want to Enter :'))
    l=[]
    for i in range(N):
        x=input().split(" ")
        command=x[0]
        if command=='insert':
            l.insert(int(x[1]),int(x[2]))
        if command=='remove':
            l.remove(int(x[1]))
        if command=='append':
            l.append(int(x[1]))
        if command=='sort':
            l.sort()
        if command=='reverse':
            l.reverse()

        if command=='pop':
            if (len(l)!=0):
                l.pop()
        if command=='print':
            print(l)
