python-for循环遍历列表-返回错误“解包的值太多”

Question

我知道该问题在网站上有很多发生，但我读过的十几本书未能解决这个简单的问题：

for df, ind_source in ["df1", "df2", "df3"], ["investingcom", "bloomberg", "ft"]:
        print(df+" "+ind_source)

返回错误值： too many values to unpack (expected 2)值too many values to unpack (expected 2)

该问题的解决方案是什么？

Answer 1

for df, ind_source in zip(["df1", "df2", "df3"], ["investingcom", "bloomberg", "ft"]):
    print(df+" "+ind_source)
