When working with floating point values, a string is converted into a floating point number using the float function. The function accepts a string as its argument and returns the floating point number which the string represents. A typical interaction would be something like:num_str = input( "Please enter a number: " )num_float = float( num_str )

We introduce the type String and show string concatenation. We also discuss what happens when you concatenate a number to a string inside of a print statement. Make sure to do this live in front of the students and ask them to predict the result of something like System.out.println(“The result is “ + 2 + 3);.

The key idea in this approach is a paradigm change for the Python code interpreter that is not easy to understand in the first place. Recursive interpreter calls are turned into tail recursion, which allows deferring evaluation by pushing frames to the frame stack, without the C stack involved.

Most programming languages have a data type called a string. A string takes care of the details for us, and we can just think of some text as a string of characters. One character might be a letter, number, or symbol, depending on the character set of the representation standard.
