Answer 1

method 1-

x=input()
evens=[i**2 for i in range(int(x)) if i**2%2==0]
print(evens)

method 2-

x=int(input())
evens=[i**2 for i in range(x) if i**2%2==0]
print(evens)

error 1 -
Input is a function, so parentheses are required.

error 2 -
input() returns string.. so interpret it to int first.. or inside range() function, as range requires int.

Still displaying same error
