获取浮点数 python 的小数位数

Question

How can I write a function that show how many decimal places each float-3 value has. How would I be able to get that?

float1= 4.9778
float2 = 6.9987475673579
float3= 4567.1     

Expected output:

4
13

Answer 1

You should not use float as a variable name. You will be unable to use it if you want to create a float variable. Your problem is easy to solve. Just use this:

num = 124.178
tmp = len(str(num).split(".")[1])
print(tmp)
