Until the python version 2, the **division of two integers was always being rounded down to 0**.

在python版本2之前， **两个整数**的**除法总是四舍五入为0** 。

Consider the below example, being executed in python version 2.7,

考虑下面的示例，该示例在python版本2.7中执行，

result = 4/5
    print(result)

**Output**

**输出量**

Other than overcoming the python version 2.7 which is mostly outdated and not a recommended version, the above-mentioned issue can be resolved while we update the python version to 3.X

除了克服python版本2.7(大多数版本已过时，而不是推荐的版本)以外，在将python版本更新为3.X时，可以解决上述问题

result = 4/5
    print(result)

**Output**

**输出量**

0.8
