Calculate variance with for loop.

Calculating the variance of the dataset in pythonThe formula for variance:Example: from statistics import mean, variance x = (1,2,3,4,5,6,7) u = mean(x) for i in x: print((sum([(i - u)**2])) / (len(x) - 1)) Incorrect output:1.250.450.050.050.451.25from statistics import variance sum([(x - sum(salaries) / len(salaries))**2 for x in salaries]) / (len(salaries) - 1) == variance(salaries) Correct output: 4.667
