CH12 程式邏輯發展練習(32-37)

(32).轉置矩陣
X=[[12,7],[4,5],[3,8]]
result=[[0,0,0],[0,0,0]]
for i in range(len(X)):
    for j in range(len(X[0])):
        result[j][i]=X[i][j]

for r in result:
    print(r)

[12, 4, 3]
[7, 5, 8]




(33).產生隨機亂數
import random
for i in range(1,10+1):
    print(random.randint(1,100),end=' ')
