R$1$M$\_$Usd, R$3$M$\_$Usd', $\text{'}$R$6$M$\_$Usd', $\text{'}$R$12$M$\_$Usd'. These four variables indicate future return in one month, three months, six months, and twelve months, respectively. In this assignment, we will use R$1$M$\_$Usd as your target variables; therefore, you will remove $\text{'}$R$3$M$\_$Usd', $\text{'}$R$6$M$\_$Usd', $\text{'}$R$12$M$\_$Usd' from the dataset.From CSV file use pandas library in python $($ please give the answer without the explanation with it make it clear and correct $)$
