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

在python版本2之前， 兩個整數的除法總是四舍五入為0 。

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

考慮下面的示例，該示例在python版本2.7中執行，

result = 4/5 print(result)

Output

輸出量

0

Other than overcoming the python version 2.7 which is mostly outdated and not a recommended version, the above-mentioned issue can be resolved while we update the python version to 3.X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(大多數版本已過時，而不是推薦的版本)以外，在將python版本更新為3.X時，可以解決上述問題

result = 4/5 print(result)

Output

輸出量

0.8
