How to display?

It shows: “123” & “Hello world in Python”

Create a variable and assign it with a number then display it.

The “a” variable can get string, int, float,…


  • a = 1 -> the variable becomes an integer variable.
  • a = 1,2: a float variable.
  • a = “Hello everyone”: a string variable.

To display the variable, you need to convert it to a string like str(a) (except with the variable can assign with string)

It shows: “1”

Math in python

The variable USD equals 1, and then that variable is multiplied by 22. When it is displayed, you must convert the type to string to display.

Display “1” and “22” and assign them to other strings.

Input, assign variable then display

Input the number you want to display the final result.
