PYTHON : mean, median, mode, and standard deviation

WITHOUT using the stats module, develop an algorithm tocalculate the following:

Create a program where :

1. User inputs real numbers until an exit code is entered.
2. The program computes and prints the mean, median,mode, and standard deviation of the dataset. The population standard deviation is the square root of thevariance. The variance is the sum of the squared deviations awayfrom the mean (entered number - mean)^2 all divided by n, the sizeof the data set.

When calculating the mean, median, mode and standard deviationPLEASE use the descriptions for step 2.(Do not use the stats module).

I am using this as a study aide so PLEASE #comment explainingeach step in the code. I am struggling in Python and wouldappreciate the help.

The program must take in the numbers the USERINPUTS in order to find the mean, median, mode andstandard deviation.
