二维数组的转换
#python3
#生成2维列表
a=list([i+5*j for i in range(1,6)]for j in range(4))
#打印列表a
print(a)
#换行打印
for i in a:
print(i)
#翻转
b=list([n[m]for n in a]for m in range(5))
#打印列表b
print(b)
#换行打印
for i in b:
print(i)
#3
c=list(i for i in range(50)if i%5==0 )
#打印列表c
print(c)
#打印列表c，每行3个元素
for i in range(len(c)):
if (i+1)%3==0:
print(c[i])
else:
print(c[i],end=",")
