Instructables开放源代码：Python索引器错误：列表索引超出范围

我在其他几个问题上看到了这个错误，但找不到答案。 {我对Python完全不熟悉，但我正在按照某个站点的说明进行操作，一旦我尝试运行脚本，就会不断出现以下错误：

import wave
import math
import struct

bitDepth = 8#target bitDepth
frate = 44100#target frame rate

fileName = "bill.wav"#file to be imported (change this)

#read file and get data

numframes = w.getnframes()

frame = w.readframes(numframes)#w.getnframes()

frameInt = map(ord, list(frame))#turn into array

    if frameOneChannel[i] > 2**15:
        frameOneChannel[i] = (frameOneChannel[i]-2**16)
    elif frameOneChannel[i] == 2**15:
        frameOneChannel[i] = 0
    else:
        frameOneChannel[i] = frameOneChannel[i]

#convert to string
audioStr = ''
for i in range(numframes):
    audioStr += str(frameOneChannel[i])
    audioStr += ","#separate elements with comma

fileName = fileName[:-3]#remove .wav extension
text_file = open(fileName+"txt", "w")
text_file.write("%s"%audioStr)
text_file.close()

索引器：列表索引超出范围

以下是脚本：

Leart-检查这些选项，它可能会有帮助：

你的输入文件格式正确吗？在我看来，你需要先生成该文件，然后才能在这个程序中使用它…在这里发布该文件

检查您的比特率和帧率是否正确

仅用于调试目的（如果代码正确，这可能不会产生正确的结果，但有利于测试）。您正在访问frameInt[4*i+1]，索引i乘以4，然后再加1（最终超出frameInt索引）。 在访问frameInt中的数组元素之前，添加“如果”以检查大小： 如果len（frameInt）>=（4*i+1）： 在第一次出现“for i in range（numframes）：”之后和“frameOneChannel[i]=frameInt[4*i+1]*2**8+frameInt[4*i]#分离通道并在新列表中存储一个通道”之前添加该语句

*注意制表符空格

哪一行引起错误？请注意，这是因为您正在访问的列表超出了它的长度。我建议，在询问更多问题之前，逐行调试代码并阅读@Pynchia在上面的评论上发布的内容。我真的不知道代码是如何工作的，所以我恐怕会重复在我把它发布到这里之前，不要把它搞砸了！错误出现在这一行：frameOneChannel[I]=frameInt[4*I+1]*2**8+frameInt[4*I]#单独的频道并将一个频道存储在新列表中感谢您的理解
