小数并未保留

python2和python3除法的最大分别:

python2:

print 500/1000

python2结果:取整数部分,小数并从未保存

0

Process finished with exit code 0

 

python3:

print 500/1000

python3结果:赢得实际结果,小数保留

0.5

Process finished with exit code 0

 

那就是说,如果python2想保留小数部分,要如何是好呢?

只必要充实二个导入包.就能够了.并无需其余操作

from __future__ import division #用于/相除的时候,保留真实结果.小数

 

追加导入包后的,python2操作:

#coding:utf-8
from __future__ import division

print 500/1000

结果:

0.5

Process finished with exit code 0

 

再有另一种格局.将除数或被除数三个别的起码三个调换到float型:

print float(500)/1000

结果:

0.5

Process finished with exit code 0
