input(function always returns string (even if the user typed in number)you can use the int(myagecode to return an integer value of the string in myage this integer value is then added to in the expression int(myage the result of this addition is passed to the str(functionstr(int(myage the string value returned is then concatenated with the strings 'you will be and in year to evaluate to one large string value this large string is finally passed to print(to be displayed on the screen let' say the user enters the string ' for myage the string ' is converted to an integerso you can add one to it the result is the str(function converts the result back to stringso you can concatenate it with the second string'in year 'to create the final message these evaluation steps would look something like the followingprint('you will be str(int(myage in year 'print('you will be str(int' in year 'print('you will be str in year 'print('you will be str in year '' in year 'print('you will be print('you will be in year 'print('you will be in year 'summary you can compute expressions with calculator or enter string concatenations with word processor you can even do string replication easily by copying and pasting text but expressionsand their component values-operatorsvariablesand function calls--are the basic building blocks that make programs once you know how to handle these elementsyou will be able to instruct python to operate on large amounts of data for you it is good to remember the different types of operators (+-*///%and *for math operationsand and for string operationsand the three data types (integersfloating-point numbersand stringsintroduced in this introduced few different functions as well the print(and input(functions handle simple text output (to the screenand input (from the keyboardthe len(function takes string and evaluates to an int of the number of characters in the string the str()int()and float(functions will evaluate to the stringintegeror floating-point number form of the value they are passed
