TypeError：list indices必须是整数或切片，而不是str

I've got two list that I want to merge in one array fo finally put it in a csv file. I'm a newbie with Python's arrays and I don't understand how I can avoid this error :

我有两个列表，我想在一个数组中合并，最后把它放在一个csv文件中。我是Python的数组的新手，我不明白我怎么能避免这个错误：

def fill_csv(self, array_urls, array_dates, csv_file_path):
    result_array = []
    array_length = str(len(array_dates))

    # We fill the CSV file
    file = open(csv_file_path, "w")
    csv_file = csv.writer(file, delimiter=';', lineterminator='\n')

    # We merge the two arrays in one

    for i in array_length:
        result_array[i][0].append(array_urls[i])
        result_array[i][1].append(array_dates[i])
        i += 1

    csv_file.writerows(result_array)

And got :

得到了：

  File "C:\Users\--\gcscan.py", line 63, in fill_csv
    result_array[i][0].append(array_urls[i])
TypeError: list indices must be integers or slices, not str

How can my count work ?

我的计数如何运作？

1 个解决方案

#1

First, array_length should be an integer and not a string:

首先，array_length应该是一个整数而不是一个字符串：

array_length = len(array_dates)

Second, your for loop should be constructed using range:

其次，你的for循环应该使用范围构造：

for i in range(array_length):  # Use `xrange` for python 2.

Third, i will increment automatically, so delete the following line:

第三，我会自动增加，所以删除以下行：

i += 1
