Question

why does the code I take from here give an error SyntaxError: invalid syntax

Answer 1

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.

Answer 2

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

Answer 3

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: "))))

Answer 4

Jahangir Kuanishbaev Because you have written wrong.

Remove > from start and end.

float("210"*int(input("2")))

Answer 5

can you share that?

Answer 6

this I took from the section converting types. I enter this and it tells me that the error. I even copied it

Answer 7

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?

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.
