The two versions have different print statement syntaxes This is one example of how Python 3 syntax can be more intuitive, making it easier for newcomers to learn Python programming. However, in Python 3, the expression 5 / 2 will return the expected result of 2.5 without having to worry about adding those extra zeroes. You would have to write it as 5.0 / 2.0 to get the exact answer of 2.5. In Python 2, if you write a number without any digits after the decimal point, it rounds your calculation down to the nearest whole number.įor example, if you’re trying to perform the calculation 5 divided by 2, and you type 5 / 2, the result will be 2 due to rounding. Unicode strings can store foreign language letters, Roman letters and numerals, symbols, emojis, etc., offering you more choices. This is important because Unicode is more versatile than ASCII. In Python 2, strings are stored as ASCII by default–you have to add a “u” if you want to store strings as Unicode in Python 2.x. In Python 3, text strings are Unicode by default.
There is better Unicode support in Python 3 There are plenty of differences between these Python programming versions, but here are five of the main ones.ģ.
