Think about it:
Strings can be used to store a string of information, so think about it Think about it, how to store the names of all classmates? Is it feasible to define 100 variables, each variable storing a student's name? Is there a better way?
Answer: List.
namesList= ['xiaoWang','xiaoZhang','xiaoHua']
is more powerful than the C language array in that the elements in the list can are of different types.
testList= [1, 'a']
Print each character of the list.
namesList = ['xiaoWang','xiaoZhang','xiaoHua'] print(namesList[0]) print(namesList[1]) print(namesList[2])
Result:
##
前面打印出列表中的每个字符,为了更有效率的输出列表的每个数据,可以使用循环来完成。
demo:
namesList = ['xiaoWang','xiaoZhang','xiaoHua'] for name in namesList: print(name)
结果:
为了更有效率的输出列表的每个数据,可以使用循环来完成
demo:
namesList = ['xiaoWang','xiaoZhang','xiaoHua'] length = len(namesList) i = 0 while i<length: print(namesList[i]) i+=1
结果:
This article explains the basics of lists in Python, introduces common list loop operations, and uses rich cases , to help everyone better understand the common basic operations of lists.
