To find the variance of all the keys in a Python dictionary (or map), you can use the statistics
and math
modules. Here's an example code snippet:
main.py288 chars13 lines
In this code, we first import the statistics
and math
modules. We then define an example dictionary my_dict
. The list()
function is used to turn the dictionary keys into a list, which we can then use in the variance()
function from the statistics
module.
Note that the variance()
function requires that you provide the mean value of the data in order to calculate the variance. We calculate this mean value using the sum()
and len()
functions, and store it in the mean
variable.
Finally, we use the print()
function to print out the variance of the dictionary keys.
