My issue

Traceback (most recent call last):
File “/mnt/sol.py”, line 6, in
lst[i].append(x)
~~~^^^
IndexError: list index out of range

My code

# cook your dish here
T = int(input())
lst = []
for i in range(T):
    x = int(input())
    lst[i].append(x)
for i in range(n):
    walk = (lst[i]*2)*5
    print(walk)

@hawarijawed
plzz refer the following solution for better understanding of the implementation

# cook your dish here
t=int(input())
for i in range(t):
    x=int(input())
    print(x*2*5)
