Use the same data file in Question $1.$ Write Python scripts with for loop to compute the mean

and standard deviation of the rainfall for any given month. The user must be able to specify

the month they wish to calculate the statistics for. Months can be represented as January: $1,$

February: $2,$ March: $3...$etc.

$\stackrel{}{x}=\frac{1}{n}{\displaystyle \underset{i=0}{\overset{n-1}{}}}{x}_i$

$x_{std}=\frac{1}{n-1}{\displaystyle \underset{i=0}{\overset{n-1}{}}}(x_i-(\stackrel{}{x}){)}^2$
