import pandas_datareader

end = "2022-12-15"
start = "2022-12-15"
stock_list = ["TATAELXSI.NS"]

data = pandas_datareader.get_data_yahoo(symbols=stock_list, start=start, end=end)

print(data)

当我运行此代码时，出现错误"TypeError: string indices must be integers"。

编辑：我已经更新了代码并将列表作为符号参数传递，但它仍然显示相同的错误

错误 ：

我想以编程方式设置 的尺寸TextView。但我正在使用sdp和ssp价值观。如何使用这些值以编程方式设置文本视图的尺寸。

TextView tasks = new TextView(this);
tasks.setText(name);
tasks.setTextSize(??);
tasks.setMargin(??)
ViewGroup.LayoutParams l1 = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, height??); // what is the height input here?

以及如何设置文本大小（ssp）和边距/填充（sdp）？

我只是在玩 for 循环并写了下面的代码。当我编写第二个 printf 语句时，编译器要求我再次声明 c 变量，当我再次声明它时，我运行代码并
得到 c + 4 的答案为 20。for 循环工作正常。为什么 c + 4 表达式产生输出 20？

#include<stdio.h>

int main()
{
  for(int c =1; c <= 10; ++c)
  {
    printf("%d\n",c);
  }
    
  int c;
  printf("%d ",c+4);
    
  return 0;
}
