Python笔记 之 tuple模块

#Tuple(元祖)
#tuple的元素不能修改，但可以包含可变元素
#tuple用’()'包裹，元素之间用逗号分隔

#01 使用可迭代元素创建元祖
#tuple(iterable=(), /)
#使用()创建仅包含一个元素的元祖时需要在元素后添加’,'防止将()认定为表达式

tp01 = (1,2,3,4,5)  
tp = (1,) 

#02 获取元素索引
#index(self, value, start=0, stop=9223372036854775807, /)

tp02 = (0,1,2,3,4,5,6,7)  
tp = tp02.index(3) 

#03 获取指定元素出现次数
#count(self, value, /)

tp03 = (0,1,2,3,4,5,6,7)  
tp = tp03.count(8) 

#04 使用下标获取元素

tp04 = (0,1,2,3,4,5,6,7)  
tp = tp04[5]  

#05 使用下标切片

tp05 = (0,1,2,3,4,5,6,7)  
tp = tp05[:5]  

#06 元祖的拼接

tp06 = ('a','b','c')  
tp = tp05 + tp06 

#07 元素判断

tp07 = (0,1,2,3,4,5,6,7)  
if 0 in tp07:  
 print('in')  

print(tp)
