Variables and types

Open a python interpreter and write the instructions in the following block list. Please note that the examples are indeed examples. Therefore, you should use different values doing your code, do not copy-paste, or you will get errors.

Create a string, e.g., my_string=Hello Jeddah. Print the variable.

Create a string that contains the text representing a number, e.g., number_string=22. Test the type of the variable, e.g., type(number_string). Print the variable.

Get a integer from the previous string, e.g., my_integer=int(number_string). Test the type of the variable, e.g., type(my_integer). Print the variable.

Get a floating from the previous string, e.g., my_floating=float(number_string). Test the type of the variable, e.g., type(my_floating). Print the variable.

Get a string from the previous floating number, e.g., my_new_string=str(my_floating). Test the type of the variable, e.g., type(my_floating). Print the variable.

Get an integer from a floating number, e.g., int(22.3). Print the variable.

Eval a string to get a number, e.g., my_eval=eval(23.8). Test the type of the variable, e.g., type(my_eval). Print the variable.

Eval a new string to get a number, e.g., my_eval2=eval(23). Test the type of the variable, e.g., type(my_eval2). Print the variable. The function eval gave a different type of variable. Say why.

Try to get an integer from the first string, e.g., my_integer_fail=int(my_string). Then, say why the operation failed.

Try to print the integer you were trying to get from a string, e.g., print(my_integer_fail). It does not work. Explain why.

Create a Boolean variable with the value False, e.g., my_bool=False. Print its value. Make a string from that variable with the str operator, e.g., my_false=str(my_bool). Note that the string is not the same as the Boolean variable. Test this concept with:

my_bool == my_false

my_bool != my_false
