Variable contents - Scott - Jun-21-2018 I mainly use SAS and it has a procedure called proc freq which lists the contents of a variable and how frequently it is populated. Does python have anything similar? Thanks RE: Variable contents - volcano63 - Jun-21-2018 It can't - variable in Python is just a placeholder for object reference, and it - the variable - may be re-assigned with reference to another object, or be deleted.

Does python have anything similar?Variable may not the right word to use if talking about Python,value in a dataset may fit better. SAS Wrote:Proc FREQ is a procedure that is used to give descriptive statistics about a particular data set.So with this info about what proc freq dos,then will Pandas fit this description right on. Pandas is used for this a lot,eg load a datasets and doing stuff like frequency count. # SAS proc freq data=mydata; tables myvar / nocol nopercent nocum; run; # Pandas mydata.myvar.value_counts().sort_index() |
