1. i 在 for 迴圈之外，怎麼還能輸出結果呢？

for i in range(1,10):
        t = 0
    print(i)

2. p為什麼沒被定義呢？因為沒有初始化

import math
import copy
import numpy as np

def main(n):
    global p
    p = np.zero([2,2])
    for i in range(0,n):
        for j in range(0,n):
            p[i,j] = i*j
    for i in range(0,n):
        for
 
 j in range(0,n):
            print(p[i,j])
if __name__ == '__main__':    
    main(2)
