试图找出Python3.5的问题。这个程序是找到一个方程的根,一旦找到了围绕着0的两个x值(一个产生正值,另一个产生负值)。我想我有一个无限循环:
from math import *
def getFunction():
func = input("Enter your function: f(x) = ")
return func
def getHighLow():
hi = eval(input("Enter an x-value that gives a positive result: "))
lo = eval(input("Enter an x-value that gives a negative result: "))
return hi, lo
def findTheZero(func, hi, lo):
delta = eval(input("How close to zero to you want to get? Within 0.01 Enter a value: "))
x = (hi + lo) / 2
while abs(eval(func)) > delta:
if x > 0:
hi = x
x = (hi + lo) / 2
else:
lo = x
x = (hi + lo)/2
return x
def main():
function = getFunction()
hi, lo = getHighLow()
print(findTheZero(function, hi, lo))
main()
