Today I will share with you an example of correctly retaining one decimal place in Python. It has a good reference value and I hope it will be helpful to everyone.
Method 1, use round function (recommended learning: Python video tutorial)
For example:
a=12.34567889 round(a,1)=12.3 保留一位小数 round(a,2)=12.35 保留二位小数
Method 2,
For example:
a=12.34567889 print(“%.1f”%a) 保留一位小数 print(“%.3f”%a) 保留三位小数 print(“%.4f”%a) 保留四位小数
Method 3,
is introduced first decima function
from decimal import Decimal a=134.5657768 t=Decimal(“134.5657768”).quantize(Decimal(“0.0”)) print(t)
Output result:
134.5
