Python 2错误:";inspect模块中存在内部Python错误

Python 2错误:";inspect模块中存在内部Python错误,python,python-2.x,Python,Python 2.x,我编写了以下代码来计算二次公式: from numpy.lib.scimath import sqrt as csqrt a = raw_input("a?") b = raw_input("b?") c = raw_input("c?") def numcheck(x): try: i = float(x) return True except (ValueError, TypeError): return False if

我编写了以下代码来计算二次公式:

from numpy.lib.scimath import sqrt as csqrt

a = raw_input("a?")

b = raw_input("b?")

c = raw_input("c?")

def numcheck(x):
    try:
       i = float(x)
       return True
    except (ValueError, TypeError):
       return False

if numcheck(a)==True:
    a=int(a)
else:
    print "a is not a number"

if numcheck(b)==True:
    b=int(b)
else:
    print "b is not a number"

if numcheck(c)==True:
    c=int(c)
else:
    print "b is not a number"


sqrt= ((b*b) - (4* (a*c)))

x_minus= (-b+(csqrt(sqrt)))/(2*a)
x_minus=str(x_minus)

x_plus= (-b-(csqrt(sqrt)))/(2*a)
x_plus=str(x_plus)

print "The solution is "+x_plus+" or "+x_minus
不管是什么蹩脚的风格,当输入不是数字时,我会出现以下错误:

ERROR: Internal Python error in the inspect module.
Below is the traceback from this internal error.

Unfortunately, your original traceback can not be constructed.

有人能告诉我为什么会发生这种情况,如果可能的话,还有一种解决方法吗?谢谢。

要进行sqrt,您只需执行以下操作:

def sqrt(num):
    return num ** 0.5

我将尝试向您提供与您的问题相关的更多信息,但现在请尝试将您的sqrt替换为该问题。

看起来像是一个IPython错误。您有没有可能改用Python 3?看起来像是一个IPython错误。您有没有可能改用Python 3?
