18 python - 列表

1.列表

1.1列表的格式

变量A的类型为列表

namesList = ['xiaoWang','xiaoZhang','xiaoHua']

比C语言的数组强大的地方在于列表中的元素可以是不同类型的

  testList = [1, 'a']

1.2 打印列表

namesList = ['xiaoWang','xiaoZhang','xiaoHua']
print(namesList[0])
print(namesList[1])
print(namesList[2])

结果：

xiaoWang
xiaoZhang
xiaoHua

2.列表的循环遍历

2.1使用for循环

namesList = ['xiaoWang','xiaoZhang','xiaoHua']
 for name in namesList:
     print(name)

结果:

xiaoWang
xiaoZhang
xiaoHua

2.2使用while循环

namesList = ['xiaoWang','xiaoZhang','xiaoHua']

  length = len(namesList)

  i = 0

  while i
