蟒蛇 - 用於遍歷列表 - 返回錯誤「太多值解壓」

Question

我知道有網站對這個問題的許多OCCURENCES，但十幾個，我讀沒能解決簡單的問題：

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

返回錯誤值：too many values to unpack (expected 2)

什麼是解決這個問題？

Answer 1

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