我正在尝试将数据列表写入 Excel 电子表格。当我尝试并行迭代整个列表时出现问题。我收到以下错误：

File "canadascript.py", line 57, in <module>
    sheet.write(row, high0_col, c.high0)
AttributeError: 'tuple' object has no attribute 'high0'

我正在导入一个单独的脚本，该脚本成功返回所有变量（high0、low0 等）。这是我收到错误时正在运行的脚本：

#!/usr/bin/env python

错误在表达式上c.high0。

如果你看看它是什么c，它是 a 的元素之一zip：

for c in zip(cities) :

这意味着它是一个元组。这就是这样zip做的：它需要一个可迭代的序列，并将其转换为一个可迭代的元组，其中每个元组都有每个序列的一个成员。

如果你能解释你对每个c人的期望，或者你打电话的原因zip，我们可能会解释如何正确地做到这一点。

我也不明白你为什么需要使用zip()，但如果你确定你需要它，试试这样：

for c in zip(cities):
    sheet.write(row, high0_col, c[0].high0)
    sheet.write(row, low1_col, c[0].low1)
    sheet.write(row, high1_col, c[0].high1)
    sheet.write(row, low2_col, c[0].low2)
    sheet.write(row, high2_col, c[0].high2)
    sheet.write(row, low3_col, c[0].low3)
    sheet.write(row, high3_col, c[0].high3)
    sheet.write(row, low4_col, c[0].low4)
    sheet.write(row, high4_col, c[0].high4)
    sheet.write(row, low5_col, c[0].low5)
    sheet.write(row, high5_col, c[0].high5)
    sheet.write(row, low6_col, c[0].low6)
    sheet.write(row, high6_col, c[0].high6)
    sheet.write(row, low7_col, c[0].low7)
    sheet.write(row, high7_col, c[0].high7)

这样，您就可以访问由zip(cities).

同样，我不明白为什么你不能使用for c in cities:，这看起来更好，但这可能会解决你的问题。
