The Calculations such as addition and subtraction don't work in python code playground
How is that suppose to work? Code playground is not a calculator that you have on your phone. You need to follow syntaxes and other things. Kindly learn the Python course further to understand.
Share the code that doesn't work.
The code playground is not Python REPL, I guess you're confusing things. In the REPL or in iPython, you can write calculations and it will output the result. It works the same way as if you had written a program doing print(1+1). However, code playground is meant for you to actually write a program. So, it's expected that 1+1 will not work. Unless, of course, you assign it to a variable: a = 1+1 ...or you input it into a function... print(1+1) Happy coding! :)
That's all I wrote
