Python how to call a function to do math-CodePudding

Such as I've defined an average function, and then I defined a variance function, and variance functions need to use mean the inside of the solution, but because of different function cannot be directly add and subtract, so what should I do?

No sample?

Is I want to make a variance, and then refer to the first mean value function, but have been an error that I mean value function is not int so can't add and subtract, the what to do,,,

CodePudding user response:

Print (res)==& gt; return res

Def scheme (li=,2,3,4,5,10,2000,30 [1]) : 
Res=sum (li)/len (li) 
Print (res) 
Return res 
Scheme () 

Def varian (li=,2,3,4,5,10,2000,30 [1]) : 
Sum2=0 
For I in range (len (li) : 
Sum1=li [0] - scheme () 
* * 2 +=sum2 sum1 
Print (sum2/len (li)) 
Varian () 

Scheme () function has a return value, in addition to the code posted, don't screenshots, typing also difficult
