the 'input' function takes a prompt string, most of the time it's a question or an instruction, this is why in my previous post I wrote int(input("Enter a number: ')) this will print 'Enter a number: ' on the screen a wait for an input when you enter 2 for example, int(input(...)) will convert it to integer. string and integer multiplication just repeat the string the integer times so "210"*2 ==> "210210" the last instruction will convert it to float float("210210") ==> 210210.0 and this will be printed out.

I'm not getting an error. I just tested: print(float("210"*int(input("2")))) With the following output using 2 as my input: >2210210.0

have you copied it with the '>' too? you should not. float("210"*int(input("Enter a number: "))) don't have a syntaxe error. you can execute it in an interpreter or print it out in a program print(float("210"*int(input("Enter a number: "))))

Jahangir Kuanishbaev Because you have written wrong. Remove > from start and end. float("210"*int(input("2")))

look. I entered your data print(float("210"*int(input ("2")))) but that's not what he gives me. what is the reason for this? 2 Traceback (most recent call last): File "./Playground/file0.py", line 1, in <module> print(float("210"*int(input("2")))) ValueError: invalid literal for int() with base 10: ''

when 2 is printed you should type a number before hitting the 'Enter' key.
