type conversion

Question

>>> float("210" * int(input("Enter a number:" )))
Enter a number: 2

How does this works?

Answer 1

the input will be converted to integer, string and integer multiplication just repeat the string:

"210"*2 ==> "210210"

the result of the multiplication will finally be converted to float. so the final output is

210210.0

Answer 2

The class str support the multiplication and division
"210"*2 = "210" + "210" = "210210"
And the content for this value is the number and the float result is 210210.0

Answer 3

1.input returns string
2.int casts value to integer
3."210" * integer value gives value times repeated "210"
because strings have different multiplication operator
4.float casts string value to real number (noninteger)

Answer 4

Thank you sir, my doubt has cleared
