# Python二維數組

T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]

## 訪問二維數組中的值

from array import *

T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]

print(T[0])

print(T[1][2])

[11, 12, 5, 2]
10

from array import *

T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]
for r in T:
for c in r:
print(c,end = " ")
print()

11 12 5 2
15 6 10
10 8 12 5
12 15 8 6

## 在二維數組中插入值

from array import *
T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]

T.insert(2, [0,5,11,13,6])

for r in T:
for c in r:
print(c,end = " ")
print()

11 12 5 2
15 6 10
0 5 11 13 6
10 8 12 5
12 15 8 6

## 更新二維數組中的值

from array import *

T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]

T[2] = [11,9]
T[0][3] = 7
for r in T:
for c in r:
print(c,end = " ")
print()

11 12 5 7
15 6 10
11 9
12 15 8 6

## 刪除二維數組中的值

from array import *
T = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]]

del T[3]

for r in T:
for c in r:
print(c,end = " ")
print()

11 12 5 2
15 6 10
10 8 12 5
