Create Arbitrary Multi-Dimensional List in Python

#!/usr/bin/python
def AllocateMList(Dim):
    if len(Dim)!=1:
        tmp=[0]*Dim[0]
        for i in range(Dim[0]):
            tmp[i]=AllocateMList(Dim[1:])
        return tmp
    else:
        return [0]*Dim[0]


#Specify Dimensions
PR=[3, 5, 7]
print "PR:", PR

#Allocate Multi-Dimensional List
TL=AllocateMList(PR)
print "TL:", TL

#Write access
TL[0][1][2]=787
print "write 787 to TL[0][1][2]"

#Check result
print "TL:", TL
