如何用循环分割数组并对其应用操作？

Question

mainArray=np.linspace(1,50,50)
##group1 is first 10 elements of mainArray    
group1=np.array(1,2,3...10)
group2=np.array(11,12,13...20)
group3=np.array(21,22,23...30)
.
.
group5=np.array(41,42,43,44,45,46,47,48,49,50)
#i need to find standart deviation and mean value of these groups
#like np.mean(group1) and np.std(group1) for all groups
#then i have to calculate (group1-meanOfGroup1)/stdOfGroup1 for all groups
#and append it to one list or array. 

我不知道如何用循环来解决这个问题，因为我的主要问题是我不能创建一个循环，将mainArray切片到组并应用平均值以及np.标准一

Answer 1

ocmean= [np.mean(oc[k:k+25]) for k in range(0,len(oc),25)]
ocstdev=[np.std(oc[k:k+25]) for k in range(0,len(oc),25)]     
d=[]

i=0
k=0
while i <len(ocmean):
    m=(oc[k:k+25]-ocmean[i])/ocstdev[i]
    i=i+1
    k=k+25
    d.append(m)

就这样解决了
