Python创建功能，获取多个输入

该代码生成了从两个列表中获取的点产生的功能。 l1在此功能中输入的点上，在l2中生成点。我要做的是编写一个生成一个函数的代码，该函数获取多个列表（输入）并生成相同的输出，但我不确定如何修改此代码以获取我想要的东西。

def get_equation(x,y):
    degree = 1
    coefs, res, _,_, _ = np.polyfit(x,y,degree, full = True)
    ffit = np.poly1d(coefs)
    print (ffit)
    return ffit
l1=[1,2,3,4]
l2=[2,4,6,8]
eq_list=(get_equation(l1,l2))

for i in (l1):
    print(round(eq_list(i)),'sadf',i)

原文

this code generates the function that results from the points taken from two lists.
The points on l1 inputted in this function, generate the points in l2.
What I want to do is to write a code that generates a function which takes multiple lists (inputs) and generate the same output but I am not sure how to modify this code to obtain what I want.

def get_equation(x,y):
    degree = 1
    coefs, res, _,_, _ = np.polyfit(x,y,degree, full = True)
    ffit = np.poly1d(coefs)
    print (ffit)
    return ffit
l1=[1,2,3,4]
l2=[2,4,6,8]
eq_list=(get_equation(l1,l2))

for i in (l1):
    print(round(eq_list(i)),'sadf',i)

如果我正确理解您，您想循环浏览输入列表并获取方程式。看看下面是否对您有帮助。

import numpy as np

def get_equation(x,y):
    degree = 1
    coefs, res, _,_, _ = np.polyfit(x,y,degree, full = True)
    ffit = np.poly1d(coefs)
    #print (ffit)
    return ffit

list_pairs = [ [[1,2,3,4], [2,4,6,8]],
               [[2,3,4,5], [4,6,8,10]],
               [[3,4,5,6], [6,8,10,12]],
               [[4,5,6,7], [8,10,12,14]] ]

for pair in list_pairs:
    print(get_equation(pair[0],pair[1]))

输出：

2 x + 1.651e-15
 
2 x + 2.581e-15
 
2 x + 3.149e-15
 
2 x - 2.141e-14

If I understand you correctly, you want to loop through a list of inputs and get the equation. See if the below helps you.

import numpy as np

def get_equation(x,y):
    degree = 1
    coefs, res, _,_, _ = np.polyfit(x,y,degree, full = True)
    ffit = np.poly1d(coefs)
    #print (ffit)
    return ffit

list_pairs = [ [[1,2,3,4], [2,4,6,8]],
               [[2,3,4,5], [4,6,8,10]],
               [[3,4,5,6], [6,8,10,12]],
               [[4,5,6,7], [8,10,12,14]] ]

for pair in list_pairs:
    print(get_equation(pair[0],pair[1]))

Output:

2 x + 1.651e-15
 
2 x + 2.581e-15
 
2 x + 3.149e-15
 
2 x - 2.141e-14

def takelist():
    mylist=list(map(int,input('list input space seperated ').split()))
    return mylist
n=int(input('number of list to input '))
for j in range(n):
    print(takelist())

输出=
输入2的列表
列表输入空间分开1 2 34
[1，2，34]
列表输入空间分离1 2 34 5
[1，2，34，5]
