使用Python实现求根公式 在数学中,求根公式(Quadratic Formula)是一种用于找到二次方程的根的方法。二次方程的标准形式为: [ ax^2 + bx + c = 0 ] 其中,a、b和c是常数,a不等于 0。根的计算过程可以由求根公式给出: [ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}
def quadratic(a, b, c, x): """Use the quadratic formula""" x_1 = (- b+(b**2-4*a*c)**(1/2)) / (2*a) x_2 = (- b-(b**2-4*a*c)**(1/2)) / (2*a) return x_1, x_2 想要了解更多,请阅读Documenting Python Code: A Complete Guide – Real Python Whitespace in...

$ python3 code.py File"code.py",line3print(i,j)^TabError:inconsistent useoftabs and spacesinindentation 您可以编写带有制表符或空格表示缩进的Python代码。但是,如果使用Python 3,则必须与您的选择保持一致。否则,您的代码将无法运行。Pep 8建议您始终使用4个连续空格来表示缩进。
$ python3 code.py File"code.py", line3print(i, j)^ TabError: inconsistent use of tabs and spacesinindentation 可以使用制表符或空格来指示缩进的Python代码。但是,如果使用的是Python 3,必须在选择上保持一致,否则,代码将无法运行 换行后的缩进 ...
$ python2 -tt code.pyFile "code.py", line 3print(i, j)^TabError: inconsistent use of tabs and spaces in indentation Python 3不允许混合制表符和空格。因此,如果使用Python 3,则会自动发出这些错误: $ python3 code.pyFile "code.py", line 3print(i, j)^TabError: inconsistent use of tabs ...

The quickest way to define a complex number in Python is by typing its literal directly in the source code:Python >>> z = 3 + 2j Although this looks like an algebraic formula, the expression to the right of the equals sign is already a fixed value that needs no further evaluation. ...
In this section, you’ll learn about the constants and how to use them in your Python code.PiPi (π) is the ratio of a circle’s circumference (c) to its diameter (d): π = c/d This ratio is always the same for any circle....
Note: The discriminant is the name given to the expression that appears under the square root (radical) sign in the quadratic formula. Test Data: The x value : 4 The y value : 0 The z value : -4 Expected Output: Two Solutions. Discriminant value is : 64.0 ...
