Python之元组 列表 多维列表 字典

1 元组 列表基本用法

将列表或者元组里的元素依次输出：
 

#元组
a_tuple=(1,23,43,5454,656,43)
b_tuple=23,434,5,3,2,3

#列表
a_list=[34,24,'qw',87,3,44,5,23]

for content in a_list:
    print(content)
for content in a_tuple:
    print(content)

输出序号和内容：

#列表
a_list=[34,24,'qw',87,3,44,5,23]

for index in range(len(a_list)):
    print(" the index",index,"number is",a_list[index])

运行结果：

 

D:\PycharmProjects\pythonProject\venv\Scripts\python.exe D:/PycharmProjects/pythonProject/hello.py
 the index 0 number is 34
 the index 1 number is 24
 the index 2 number is qw
 the index 3 number is 87
 the index 4 number is 3
 the index 5 number is 44
 the index 6 number is 5
 the index 7 number is 23
