Question

我不知道为什么当我试图跑步时出现。我试图解决但我无法解决。有什么错误吗？

import math

print(" Hello....\n This program will ask you to enter 3 numbers \n (a, b and c) that will be used in the quadratic formula to \n calculate the roots of an equation ")

a=float(input("Enter a Value for a: "))

while(a <= 0):

print(" Please enter a number that is larger than 0.") <br/>
a=float(input("Please enter a value for A: "))

b=float(input("Enter a Value for b: "))

while(b <= a): <br/>
print(" Please enter a value that is larger than A.") <br/>
b=float(input("Enter a value for B: "))

c=float(input("Enter a Value for C: "))


root1 = float(-b + math.sqrt(b * b - 4 * a * c)/(2 * a)) <br/>
root2 = float(-b - math.sqrt(b * b - 4 * a * c)/(2 * a))

print("Root 1 is " , root1)<br/>
print("Root 2 is " , root2)<br/>
input("prompt: ")

首先：在Python中，缩进是必须的。嵌套代码缩进是一种语法特征，而不是用paranthesis'来源代码来源。

第二：显然，你从某个地方复制粘贴的HTML代码。摆脱<br />。

python期望一个缩进块
