Question

我的代码的第12行和第13行不影响该程序。

当前输出：

嗨10

hola 10

期望的输出：

嗨10

hi 6

hola 10

CSV输出右栏中的第二个数字应更改为6而不是10（由于第12行和第13行）为什么这些行没有影响？

感谢您的任何帮助或想法。

    for a in range(0, len(levels)):
        if levels[a] == ["3"]:
            greeting = "hola"
            food = Row(levels[a], greeting)
            food.rowEntry(levels[a], greeting)
        else:
            greeting = "hi"
            food = Row(levels[a], greeting)
            food.rowEntry(levels[a], greeting)

Answer 1

if level == [2]:需要使用字符串'2'而不是数字2才能将该条件评估为True。你在if levels[a] == ["3"]:的不同行中做对了。
