For the first Output = [3, 8, 7, 9] I had given manual input and for the second Output = ['3', '8', '7', '9'] I had asked for an input list. So, now I am wondering both being the lists what could be the diff?

    One list contains int elements. The other contains string elements. I assume this is because you created a for loop asking for string inputs. Yes you entered integers but python changed them to string. ```(input("Enter a number"))``` I assume – Buddy Bob Apr 04 '21 at 03:20

One list contains integer (int) values, while the other contains string (str) values. An integer value can be used in mathematical equations and mathematical comparisons (for instance, if x > 0), while string values are usually used to display words or text, and cannot be used in equations. For instance, if you had

string_var = "1"
int_var = 1

print(int_var * 2)
print(string_var * 2)

The string variable (in quotes) cannot be multiplied (it instead returns 11, which obviously isn't correct. The integer variable is multiplied successfully. Strings are better used when saving words or non-number values into a variable. You can research more on strings and integers online.

as BuddyBobIII said, all of the first list elements are ints which refers to Integers as whole numbers, but the second one are strings which refers to text elements and cannot use in mathematical operations.

if you want to change the second to integers, you can use map function to change all elements of an iterable variable to integers:

a = ['1','2', '3' , '4']

print(list(map(int, a)))

Output:

[1, 2, 3, 4]
