所以我是 python 的新手,但已经成功地创建了可以计算面积、体积、将摄氏度转换为华氏度等的程序……但是,我似乎在使用这个“直线斜率”程序时遇到了一些麻烦。
# A simple program which prompts the user for two points
# and then computes and prints the corresponding slope of a line.
# slope(S): (R*R)*(R*R) -> R
# If R*R is a pair of real numbers corresponding to a point,
# then slope(S) is the slope of a line.
def x1(A):
def y1(B):
def x2(C):
def y2(D):
def slope(S):
return (D-B)/(C-A)
# main
# Prompts the user for a pair of points, and then computes
# and prints the corresponding slope of the line.
def main():
A = eval(input("Enter the value of x1:"))
B = eval(input("Enter the value of y1:"))
C = eval(input("Enter the value of x2:"))
D = eval(input("Enter the value of y2:"))
S = slope(S)
print("The slope of a line created with those points\
is: {}{:.2f}".format(S,A,B,C,D))
main()
最佳答案
斜率函数可能类似于以下内容 - 一个采用四个参数的函数,代表这两个点的四个坐标:
def slope(x1, y1, x2, y2):
return (y1 - y2) / (x1 - x2)
但显然不应该这么简单,还得细化一下,考虑x1 == x2的情况。
