\mymulticolumn{1}{x{5.377cm}}{Print: In Python 2, "print" is treated as a statement rather than a function. There is no need to wrap the text you want to print in parentheses, although you can if you want. In contrast, Python 3 explicitly treats "print" as a function, which means you have to pass the items you need to print to the function in parentheses in the standard way, or you will get a syntax error. \newline % Row Count 8 (+ 8)
Integer Division: Python 2 treats numbers that you type without any digits after the decimal point as integers. For example, if you type the expression 3 / 2 in Python 2 code, the result of the evaluation will be 1, not 1.5 as you might expect. Python 3 evaluates 3 / 2 as 1.5 by default, which is more intuitive for new programmers.% Row Count 15 (+ 7)
