Every programming language changes significantly between major versions after the release of an update. In this article, Vinodh Kumar explains some of the major differences between Python 2 and Python 3 with examples to help illustrate the changes in the language.
This tutorial focuses on the following.
- expression (math.)
- Print Options
- Unequal operation
- automatic migration
- Performance issues
- Major internal service changes
(located) at Python 2 in order to obtain the calculation expression (math.)， You would type：
But in Python 3, you would type.
Thus, whatever we enter, the values are assigned to the variables x in 2 and 3. When you type 2*6 in Python 2, the result will be 12, which is the evaluation value.
However, when the same program is run in Python 3, the result is a string value. In this case, it looks like 2*6 in string format.
or so， How we get assessments expression (math.) this (Cantonese)？ present .， We have to use a file called eval of expression (math.) or function。 When you write before you enter eval time， It will bring expression (math.) Convert to calculated value。
Examples of specific expressions.
In Python 2.
