基于计算器的二次图辅助Python

Question

大家好，我正试图为我在学校的数学课编写一个二次图辅助工具

这些年来，我编写了一些其他数学工具，所有这些工具都工作得相当好。但是，当我尝试将此新代码加载到计算并运行时，它表明存在语法错误。我相信计算器（fx-CG50 AU）是在micropython上运行的，据我所知，它与micropython类似，但更区分大小写，所以我尽了最大努力，通过改变大小写，在操作符之间加空格等，使它工作了几个小时，但没有成功。任何帮助和建议都将不胜感激：）。代码如下：

print('Ax ^ 2 + Bx + C')

astr = input('A: ')

bstr = input('B: ')

cstr = input('C: ')

a = float(astr)

b = float(bstr)

c = float(cstr)

delta = (b ** 2) - (4 * a * c)

print('discriminant:', delta)

if delta == 0:
    
    x1 = float((((-1 * b) - (delta ** 0.5) / (2 * a))))
    
    x1int = int(x1)
    
    
    if x1 == x1int:
        
        print('x intercept: (', x1, ', 0)')
    

    else:
        
        sb = float(-1 * b)

        sa = float(2 * a)
        
        print('x intercept: ( (', sb, ' + sqr(', delta,'))/', sa,'), 0)')

    if a > 0:
        print('Nature of Graph is: Cuts the x-axis twice. Concave up.')

    elif a < 0:
        print('Nature of Graph is: Cuts the x-axis twice. Concave down.')

    else:
        print('this aint no quadratic tho')




elif delta > 0:

    x1 = float((((-1 * b) - (delta ** 0.5) / (2 * a))))

    x2 = float((((-1 * b) + (delta ** 0.5) / (2 * a))))
    
    x1int = int(x1)

    if x1 == x1int:

        print('x intercepts: (', x1, ', 0)', ' and (', x2, ', 0)' )
    

    else:
        
        sb = -1 * b

        sa = 2 * a
        
        print('x intercepts: ( (', sb, ' + sqr(', delta,'))/', sa, '), 0) and ( (', sb, ' - sqr(', delta,'))/', sa, '), 0)') 

    if a > 0:
        print('Nature of Graph is: Cuts the x-axis once. Concave up.')

    elif a < 0:
        print('Nature of Graph is: Cuts the x-axis once. Concave down.')

    else:
        print('this aint no quadratic tho')



elif delta < 0:

    print('No x intercepts')
    
    if a > 0:
        print('Nature of Graph is: Lies entirely above the x-axis. Concave up. Positive definite.')

    elif a < 0:
        print('Nature of Graph is: Lies entirely below the x-axis. Concave down. Negative definite.')

    else:
        print('this aint no quadratic tho')

else:
    
    print('error....!.')

print('y intercept: (0, ', c, ')')

xvcord = float((-1 * b) / (2 * a))

yvcord = float((a * ((xvcord) ** 2)) + (b * (xvcord)) + c)

xvcordint = int(xvcord)

yvcordint = int(yvcord)

if xvcordint == xvcord:
    
    if yvcordint == yvcord:
        
        print('vertex: (', xvcord, ', ', yvcord, ')')

    else:
        
        top = -1 * ( b ** 2) + ( 4 * a * c)
        bot = 4 * a


        print('vertex: (', xvcord, ', ',top, '/', bot, ')') 

else:
    
    if yvcordint == yvcord:
        
        top = -1 * b
        bot = 2 * a
        print('vertex: (', top, '/', bot, ', ', yvcord, ')')

    else:
        
        topx = -1 * b
        botx = 2 * a
        
        topy = -1 * (b ** 2) + (4 * a * c)
        boty = 4 * a


        print('vertex: (', topx, '/', botx, ', ',topy, '/', boty, ')') 

计算器上的错误输出为SyntaxError:无效语法。计算器没有说明这个错误发生在哪里等

它最初是在一个while循环中，带有涂鸦，但我把它们拿出来，试图把它剥离到基本的部分，这样我就可以缩小它的范围：）

提前谢谢
