python tutorial on calculations with arithmetic operations
In this program, we first use the input() function to prompt the user to enter the first number, the operator, and the second number. The float() function is used to convert the user input from a string to a floating-point number.
Next, we use a conditional statement (if, elif, else) to perform the appropriate arithmetic operation based on the operator entered by the user. If the operator is not one of the four supported operators (+, -, *, /), we print an error message.
Finally, we use the print() function to output the result of the calculation.
When you run this program, it will display the prompts for the first number, operator, and second number in the terminal. The user can then enter the values and press enter. The program will take the user's input, perform the calculation, and print out the result
