Python“列表分配索引超出范围”

我是Python和编程方面的新手

我应该制作一个python程序，打开两个文件，其中包含随机数，并创建一个新文件，其中的数字从最低到最高排列

因此，我编写了这段代码，它使用两个for循环遍历所有数字，搜索最低的、非常基本的内容，然后存储数字及其位置，附加到一个Lmix列表，该列表将保存在最终文件中，并存储数字位置以从该列表中删除它，这样就不会再次找到它

变量是葡萄牙语的，但我在评论中翻译了它们，其余的都是不言自明的

arq1 = open("nums1.txt","r")
arq2 = open("nums2.txt","r")

arqmix = open("numsord.txt","w")

L1 = arq1.readlines()
L2 = arq2.readlines()
Lmix = []

L1 = list(map(int,L1)) # converts lists into int
L2 = list(map(int,L2))

cont = 0

menor = L1[0]  # "Menor" is the variable that stores the lowest number it finds
menorpos = 0   # "Menorpos" is the position of that variable in the list, so it can delete later
listdec = 0    # "listdec" just stores which list the number was from to delete.

while cont != (len(L1)+len(L2)):   

# while loops that finds the lowest number, stores the number and position, appends to the Lmix and deletes from the list so it won't be found on next   iteration

    n = 0
    for n,x in enumarate(L1):
        m = 0
        for m,y in enumarate(L2):
            if x<menor:
                menor = x
                menorpos = n
                listdec = 0
            elif y<menor:
                menor = y
                menorpos = m
                listdec = 1
            m += 1
        n += 1

    Lmix.append(menor)
    if listdec == 0:
        del L1[menorpos]
    elif listdec == 1:
        del L2[menorpos]
    cont += 1

for x in Lmix:
    arqmix.write("%d\n"%x)

arq1.close()
arq2.close()
arqmix.close()

但每次运行时，都会出现以下错误：

回溯最近一次呼叫上次： 文件C:/Users/Danzmann Notebook/pycharm项目/untitled/aula18.py，第41行，in del L2[menorpos] 索引器：列表分配索引超出范围

我知道这意味着什么，但我就是不明白为什么会发生，我怎么才能解决它

任何帮助都将不胜感激

提前感谢，抱歉出现语法错误，英语不是我的母语。

为了调试这一点，我在while循环中添加了两个print语句-这是我看到的：

Cont: 0  L1 [9, 2, 6, 4, 7]  L2 [3, 15, 5, 8, 12]  Lmix []
  Found menor 2 menorpos 1 listdec 0

Cont: 1  L1 [9, 6, 4, 7]  L2 [3, 15, 5, 8, 12]  Lmix [2]
  Found menor 2 menorpos 1 listdec 0

Cont: 2  L1 [9, 4, 7]  L2 [3, 15, 5, 8, 12]  Lmix [2, 2]
  Found menor 2 menorpos 1 listdec 0

Cont: 3  L1 [9, 7]  L2 [3, 15, 5, 8, 12]  Lmix [2, 2, 2]
  Found menor 2 menorpos 1 listdec 0

Cont: 4  L1 [9]  L2 [3, 15, 5, 8, 12]  Lmix [2, 2, 2, 2]
  Found menor 2 menorpos 1 listdec 0

Traceback (most recent call last):
  File "<pyshell#30>", line 29, in <module>
    del L1[menorpos]
IndexError: list assignment index out of range

您不需要显式地增加m和n。这已经为你做了。这可能会导致索引超出范围

    m += 1
n += 1

为什么在for循环中显式增加m和n？这已经为你做了。

    m += 1
n += 1
