从随机生成的数字中计算一个值，该值总是正数

Question

我试图确保值tDiscriminant总是正的。正如您在下面看到的，它是由三个随机生成的数字计算出来的

s = random.uniform(1,100)
sRounded = round(s,1)   
v = random.uniform(1,50)
vRounded = round(v,1)   
a = random.uniform(1,20)
aRounded = round(a,1)
tDiscriminant = (vRounded*vRounded)-(2*aRounded*sRounded)
tDiscriminantRooted = math.sqrt(tDiscriminant)

如果tDiscriminant为负，那么s、v和a的值必须再次生成，直到tDiscriminant为正

Answer 1

试试看

import random
tDiscriminant = -1
while tDiscriminant <= 0:
  s = random.uniform(1,400)
  sRounded = round(s,1)   
  v = random.uniform(1,50)
  vRounded = round(v,1)   
  a = random.uniform(1,20)
  aRounded = round(a,1)
  tDiscriminant = (vRounded*vRounded)-(2*aRounded*sRounded)
tDiscriminantRooted = math.sqrt(tDiscriminant)
