why is this variable not printing out properly?

[IAMK]

The recommended way would be to use format.  String concatenation in general is not a great technique (though often the first thing taught >.>)

var1 = 2 + 2
 
print('The result of all calculations is {} and we are done.'.format(var1))

Could you please explain why that is?
To me, a simple typecast to string seems cleaner.
