如何使用PYTHON中的随机行和列生成具有1-9之间的随机数的矩阵

Question

This is my code, and it's not printing anything. Help, please.

import random

row=random.randrange(5,9)
col=random.randrange(5,9)
def matrix(row, col):
    c=[]
    for i in range (row):
        temp=[[],[]]
        for j in range (col):
            a=random.randrange(1,9)
            temp.append(a)
        c.append(temp)

    for square in c:
        print square

Answer 1

try this

import random

row=random.randrange(5,9)
col=random.randrange(5,9)
def matrix(row, col):
   return [[random.randrange(1,9) for a in range(row)] for b in range(col)]

print matrix(row,col)
