Basic Functions (your first program)

Print function

The print function display a string value inside the parenthesis on the screen

print('Hello world')
print( 'I hope you have a nice day')

The input function

The input function waits that the user put some text on the keyboard and press enter

The Len Function

You can pass a len value string value  and it will reply with the number of character on that string

here is another example

Now let see what happens if you try to put together something like 

I am 30 years old

print(' I  am '  + 30  + 'years old')

You need to pass 30  as a string

Now let see how all of them work together
