A.list(range(1,7,2))
B.list(range(1,5,2))
C.[x for x in range(7) if x%2!=0]
D.[2*x+1 for x in range(3)]
A.range()函数是一个内置函数
B.range()函数返回的是一个可迭代对象(类型是对象),而不是列表类型
C.list(range())可以把range()函数返回的可迭代对象转为一个列表。
D.list(range(5))返回的列表中的列表项的数据类型是字符串类型
A.for i in lst: i=i**2 print(lst)
B.for i in range(0,3): lst[i]**=2 print(lst)
C.for i in range(0,3): lst[i]=i**2 print(lst)
D.for i in range(0,3): lst[i]+=lst[i] print(lst)
