我有两个数据框,即共享和 Log_Returns。我想将第一个数字与 Log_Returns 的第一列相乘。第 2 列的第 2 位股份,依此类推。
我试过 for 循环但没有输出,我也有错误。
我试过这段代码,但没有输出

i=0
for j in range(Log_Return.shape[1]):
#j chooses the column of Log data frame
#shape[1] gives number of columns
for k in range(len(Log_Return)):
# k chooses the rows one by one of jth column
shares.iloc[i,0]*Log_Return.iloc[j,k]
#you can multiply and even store the values or do any operations you want
i+=1
#i determines the row of shares data frame
但我得到这个错误
